1 VALVES V-Series Two-way and Three-way Globe Valve Bodies, Components and Assemblies F e a t u r e s : Heating and cooling applications for non-corrosive fluids Steam and hot water flow control Complete valve assemblies or components available Electric or hydraulic actuators and linkages Two-way flow and three-way mixing and diverting valves 1/2" to 6" valve sizes The high quality V-Series two - w ay and thre e - w ay globe va l ves are manu fa c t u red to exact specifications and are designed to provide years of re l i abl e s e r v i c e. The assemblies are designed for heat i n g / cooling ap p l i c ations using steam, wat e r, glycol or other non-corro s ive fl u i d s. The V-Series assemblies should not be used with combustible f l u - ids such as na t u r al gas. The V-Series pro d u c t s a re ava i l able as complete assemblies but most users purchase the bodies, actuators and linkage s s ep a r at e ly for convenient local assembly. Valve Bodies Va l ve bodies are ava i l able in the two - w ay configur ation with stem-up open (norm a l ly open) and stem-up closed (norm a l ly closed) ve r s i o n s. Th re e - w ay mixing and dive rting va l ve bodies are also ava i l abl e. Va l ve body sizes range from 1/2 inch to 6-inch pipe and 5/8" O. D. copper tube size. Va l ve b o dy styles include; screw thread, union and fl a re d in cast bro n ze, fl a n ged in cast iro n. Actuators D epending upon the ap p l i c ation, three classes of o u r a c t u ators are suitable for use with our va l ve bodies; linear stro ke hyd r a u l i c, linear stro ke electric and rotary stro ke box style actuat o r s. See the Actuat o r s section of this cat a l og for complete details. Linkage kits Most actuators re q u i re mechanical linkage kits speci f i c a l ly designed to couple them to the va l ve bodies. S everal varieties of l i n k age kits are ava i l able to mat ch the va l ve bodies to our range of a c t u ators for va r i o u s ap p l i c at i o n s. Complete assembly instructions are supplied with each kit. Complete Valve Assemblies Complete va l ve assemblies consist of a va l ve body and selected actuator coupled by a mat ching linkage kit. Usually customers order the body, actuator and l i n k age kit indiv i d u a l ly and easily assemble their ow n va l ve assembl i e s. Howeve r, among the many possibl e c o m b i n ations of b o d i e s, actuators and linkage s, there a re several standard ones that may be ord e red from the factory as completely pre - a s s e m bled va l ve assembl i e s. 3-2

2 Valve Model Code Refer to the sample va l ve model code below for the fo rm at to use when specifying model nu m b e r s. When va l ve bodies only are being specified, the C o n t rol Fo rm field will alw ays be specified as "VB" and the Actuator field will alw ays be "000". When a complete factory assembled va l ve is being specified, the Control Fo rm field will ch a n ge to one of f ive options (VA, VC, VF, VP, or VS), dep e n d i n g upon the type of c o n t rol action delive red by the selected actuat o r. The actuator and mat ching l i n k age for this Control Fo rm are then identified in the Actuator field by replacing the "000" with a p rescribed three-digit code identifier for the selected combination. This three-digit code is only used when specifying ava i l able factory assembl e d va l ve s. A description of ava i l able 3-digit codes fo r the Actuator field, wh i ch specifies factory assembled va l ves is given in the Va l ve Assembly Tabl e s b eginning on page Sample Ordering Codes for Va l v e s : Control Form Body End Fitting Actuator Pattern Valve Size Control Form Body End Fitting Pattern Valve Size Port PP Code* Valve Body V B Valve body only, no actuator Valve Assemblies VA Actuator with two position ON-OFF spring return V C Actuator with two position ON-OFF nonspring return V F Actuator with floating control non-spring return V P Actuator with proportional control and slidewire feedback V S Actuator with proportional control and analog input Tw o -Wa y Stem up open, brass trim with disc, 1/2" to 2" Stem up open, brass trim with disc, 2-1/2" to 6" Stem up closed, brass trim with disc, 1/2" to 2" Stem up open, s.s trim with disc, 1/2" to 2" Stem up closed, s.s trim with disc, 1/2" to 2" Stem up open, s.s trim, 1/2" to 2" Stem up closed, s.s trim, 1/2" to 2" T h r e e -Wa y Mixing, 1/2" to 2" Mixing, 2-1/2" to 6" Diverting, 1/2" to 2" Diverting, 2-1/2" to 6" 1 U n i o n 2 F l a r e d 3 Screwed or f l a n g e d 4 Union sweat Actuator None, valve body o n l y X X X A c t u a t o r / l i n k a g e assembly code for factory assembled u n i t s 3 A n g l e 4 S t r a i g h t a w a y 5 Globe, flanged 0 1 1/2 inch, reduced port 0 2 1/2 inch, reduced port 0 3 1/2 inch, reduced port 0 4 1/2 inch 0 5 3/4 inch, reduced port 0 6 3/4 inch inch, reduced port 08 1 inch /4 inch /2 inch 11 2 inch /2 inch 13 3 inch 14 4 inch 15 5 inch 16 6 inch * Size codes for 1/2" to 6" valve size 3-3

3 VALVES Valve Selection How to Select a Valve E a ch va l ve assembly consists of a va l ve body, an a c t u ator and a linkage kit. The instructions and t ables in this cat a l og will guide you in selecting the proper components or factory assembl i e s. 1. Determine the Application Criteria Fl ow type re q u i red t wo - w ay, equal % or modified linear t h re e - w ay, mixing or dive rt i n g Fluid type (hot wat e r, steam, glycol, etc. ) Fluid temperat u re Inlet pre s s u re re q u i re d Existing piping or tubing size 2. Determine Valve Control Form Required The Control Fo rm specifies the type of c o n t ro l action for the va l ve assembly. Th e re are six diff e r- ent control fo rm s. Fo rm VB specifies the va l ve b o dy only. Determine the desired Control Fo rm for the va l ve assembly in your ap p l i c ation from the table below. 3. Determine Required C V G e n e ral info rmation and guidance on valve sizing is presented in pages 3 35 to Sizing the valve is the most important valve selection criteria For Control Fo rm VA and VC (ON-OFF), C V value does not affect va l ve body selection. Use the largest C V ava i l- able in the desired pipe size to size the va l ve. For Control Fo rm VF, VP and VS (fl o ating and pro p o r- tional control), go to the section in this cat a l og on va l ve sizing (pages 3 35 to 3 43) to determine the C V n e e d e d for the ap p l i c ation. To determine C V, the fo l l ow i n g parameters must be identified: inlet pre s s u re fluid temperat u re fluid specific gr av i t y fluid fl ow rate in GPM (liquid).. or fluid fl ow rate in lbs./hr (steam) Valve Assembly Control Form Form Control Action Spring Actuator* Input Signal VB None None None Valve body only VA Two Position, ON-OFF Spring Return (NO/NC) RSE Dry contact, single input VC Two Position, ON-OFF Non-Spring Return RSE Dry contact, dual input VF Floating Non-Spring Return LSE Dry contact, dual input VP Proportional, slidewire feedback Spring Return (NO/NC) RSE Dry contact, dual input VP Proportional, slidewire feedback Non-Spring Return RSE Dry contact, dual input VS Proportional, analog input Spring Return RSE Analog VS Proportional, analog input Spring Return LSH Analog VS Proportional, analog input Non-Spring Return RSE, LSE Analog * L S E : linear stroke electric L S H : Linear stroke hydraulic R S E : Rotary stroke electric 3-4

4 Valve Selection 4. Select Valve Body For Control Fo rm VA or VC (ON-OFF), use the criteria identified in (1.) ab ove to select the desired va l ve b o dy. Make sure the va l ve body selected has a pre s- s u re rating suitable to the fluid pre s s u re. Specify the largest C V r ating in the desired pipe or tubing s i ze for that selected va l ve body. Remember that ON- OFF control action re q u i res an electric actuator that uses the stem-up open version of the va l ve body only. I f the selected electric actuator is a spring re t u rn t y p e, the va l ve can be configured norm a l ly open or normally closed as determined by assembly of t h e a c t u ator linkage. For Control Fo rm VF (fl o ating), only an electric a c t u ator and only the stem-up open version of t h e va l ve body that meets the ap p l i c ation criteria may be used. Make sure the va l ve body selected has a p re s s u re rating equal to or gre ater than the fl u i d p re s s u re. For the chosen va l ve body, select a va l ve s i ze (PP code) whose C V is nearest to the C V d e t e r- mined from va l ve sizing. In some cases this ch o i c e m ay re q u i re the piping size to be reduced to fit the selected va l ve. For Control Fo rm VP or VS (pro p o rtional contro l ap p l i c ations) using electric actuat o r s, you may select only the stem-up open version of the va l ve b o dy that meets the ap p l i c ation criteria (stem-up closed actuators re q u i re a hydraulic actuator). M a ke sure the va l ve body selected has a pre s s u re r ating equal to or gre ater than the fluid pre s s u re. I f the selected actuator is a spring re t u rn type, the va l ve can be configured norm a l ly open or norm a l ly closed as determined by the selection of the actuat o r. For the chosen va l ve body, select a va l ve size (PP code) whose C V is nearest to the C V d e t e rmined fro m va l ve sizing. In some cases this choice may re q u i re the piping size to be reduced to fit the selected va l ve. For Control Fo rm VS (pro p o rtional control ap p l i c a- tions) using hydraulic actuat o r s, select either the stem-up open or stem-up closed va l ve body that meets the ap p l i c ation criteria Make sure the va l ve body selected has a pre s s u re rating suitable to the fl u i d p re s s u re. For the chosen va l ve body, select a va l ve s i ze (PP code) whose C V is nearest to the C V d e t e r- mined from va l ve sizing.. Remember hydraulic a c t u ators may only be used with va l ve sizes up to 2". This choice may re q u i re the piping size to be reduced to fit the selected va l ve. 5. Select the Actuator For the chosen Control Fo rm, consult the actuat o r selection table on page 3 18 for an ove r v i ew of t h e a c t u ator types, control action, torque and trave l time to assist in determining the full actuator s p e c i f i c ation. Note that there are many models o f a c t u ators ava i l able from the company in our c at a l og, but only those with 180 of t r avel and those with ava i l able linkage kits may be used for control of our va l ve s. Control Form V A Electric Ro t a ry Actuator, two position with spring re t u rn and single contact input For an electric actuator with two-position ON-OFF c o n t rol action and spring re t u rn, select the EA12 a c t u at o r. The EA12 may be configured for norm a l ly open or norm a l ly closed operation by the selection o f the ap p ro p r i ate actuator linkage. Check the cl o s e - o ff p re s s u re table on page 3 22 to determine i f the EA12 actuators have enough torque to shut the va l ve against the expected inlet pre s s u re criteria at the va l ve size selected. Check any temperat u re restrictions on use of this actuator as noted on the t e m p e r at u re tables on page Control Form V C Electric Ro t a ry Actuator, two position with non-spring re t u rn and single contact input For an electric actuator with two-position ON-OFF c o n t rol action and non-spring re t u rn, select the EA31 actuat o r. Check the cl o s e - o ff p re s s u re table on page 3 23 to determine if the EA31 actuat o r s h ave enough torque to shut the va l ve against the expected inlet pre s s u re criteria at the va l ve size selected. Check any temperat u re restrictions on use of this actuator as noted on the temperat u re t ables on page

5 VALVES Valve Selection Control Form VF Electric Linear Actuator, floating control with non-spring re t u rn and dual contact input For fl o ating control action the MF or MF a c t u ator style must be selected. Check the cl o s e - o ff p re s s u re table on page 3 24 to determine if t h e s e a c t u ators have enough fo rce to shut the va l ve against the expected inlet pre s s u re criteria at the va l ve size selected. This pre s s u re rating must be higher than the fluid inlet pre s s u re in the ap p l i c a- tion criteria. Also ch e ck any temperat u re re s t r i c- tions on use of this actuator as noted on the t e m p e r at u re tables on page Control Form VP Electric Ro t a ry Actuator, proportional control with s l i d ew i re fe e d b a ck, spring re t u rn and dual contact input. Note that floating control action can be accomplished in Control Fo rm VP if s l i d ew i re fe e d b a ck is i g n o re d. For spring re t u rn pro p o rtional control action, the b ox style Models EA42 or EA44 low torque electric a c t u ator may be used. These actuators may be configured for norm a l ly open or norm a l ly closed operation by the assembly o f the ap p ro p r i ate actuator linkage. Check the cl o s e - o ff p re s s u re table on page 3 22 to determine if t h e EA4x actuator has enough torque to shut the va l ve against the expected inlet pre s s u re criteria at the va l ve size selected. This pre s s u re rating must be higher than the fluid inlet pre s s u re in the ap p l i c a- tion criteria. Also ch e ck any temperat u re re s t r i c- tions on use of this actuator as noted on the temperat u re tables on page Electric Ro t a ry Actuator, proportional control with slidew i re fe e d b a ck, non-spring re t u rn and dual contact input. For pro p o rtional control action with non-spring re t u rn, the medium torque models EA52, EA54, EA56 and EA58 and high torque EA76 electric a c t u ators with dual contact input may be used. C h e ck the cl o s e - o ff p re s s u re tables on page 3 22 to 3 24 to determine if the EA5x or EA76 actuator has enough torque to shut the va l ve against the expected inlet pre s s u re criteria at the va l ve size selected. Th i s p re s s u re rating must be higher than the fluid inlet p re s s u re in the ap p l i c ation criteria.

6 Valve Selection Electric Linear Actuator, floating control with non-spring return and optional analog input. The MF non-spring re t u rn linear stro ke electric actuator with fl o ating input (Control Fo rm VF) m ay be conve rted to an analog input actuat o r ( C o n t rol Fo rm VS) by the addition of an optional a n a l og input card (MFC-420 for current or MFC-8000 for vo l t age). Check the cl o s e - o ff p re s s u re table on p age 3 24 to determine if the MF actuator with analog input has enough torque to shut the va l ve against the expected inlet pre s s u re criteria at the va l ve size selected. This pre s s u re rating must be higher than the fluid inlet pre s s u re in the ap p l i c ation criteria. Also ch e ck any temperat u re restrictions on use of this actuator as noted on the t e m p e r at u re tables on page Hydraulic Linear Actuator, proportional control, spring return, analog input For pro p o rtional control action the EA81 hyd r a u l i c a c t u ator accepts a 4-20mA input signal and is our most economical actuator for smaller va l ve assembl i e s. Note that the EA81 should not be used with fluid temperat u res below 40 F. Check the cl o s e - o ff p re s s u re table on page 3 25 to determine if the EA81 a c t u ator has enough torque to shut the va l ve aga i n s t the expected inlet pre s s u re criteria at the va l ve size selected. This pre s s u re rating must be higher than the fluid inlet pre s s u re in the ap p l i c ation criteria. Also ch e ck any temperat u re restrictions on use of this actuator as noted on the temperat u re table on p age Options Note that options can be specified in the actuat o r model code, even though they are not listed in the A c t u ator Selection Table on page Unless noted as ava i l able factory assemblies in the Va l ve A s s e m bly Tables commencing on page 3 27, selecting a c t u ators with options re q u i res that the actuat o r, va l ve body and linkage kit be purchased as sep a r at e i t e m s. 6. Select the Linkage Kit The suitable va l ve / a c t u ator combinations are listed in detail with part numbers in the Va l ve A s s e m bly Tables beginning on page Th e s e t ables provide the part number of the mech a n i c a l l i n k age kit that couples the selected actuator to the desired va l ve body for that ap p l i c ation. The MF series, when used with 2" or smaller va l ve s, re q u i res no linkage. 7. Valve Assemblies vs Valve Components Once the va l ve body, actuator and linkage are selected, they may be ord e red in one of t wo way s. It may be ord e red fully assembled if the combination is an ava i l able factory va l ve assembly. Ava i l able fa c t o r y a s s e m blies are noted in the Va l ve Assembly Tabl e s commencing on page The part number will commence with the code that designates the Contro l Fo rm (VA, VC, VF, VP, VS). Only those entries in the column Ava i l able factory assemblies may be o rd e red as full assembl i e s. Note that the actuat o r re c e ived with this assembly must confo rm to the c o n f i g u r ation of the actuator specified for that entry. A ny other actuator configuration of options not s p e c i f i c a l ly delineated cannot be ord e red as a fa c t o- ry assembled va l ve. I f the selected assembly is not listed as an ava i l abl e factory assembly, the va l ve assembly must be o rd e red as body, actuator and linkage components and assembled locally using the complete instru c- tions provided with the linkage kit. When ord e r i n g the va l ve body, actuator and linkage sep a r at e ly, the full model numbers for these components must be specified (see the Actuators section of this cat a l og ). 8.

7 VALVES Two-Way Valve Bodies Introduction Va l ve bodies are ava i l able in two - w ay configurat i o n with stem-up open and stem-up closed configurat i o n s. Stem-up closed models are restricted to use with hydraulic actuat o r s. The linkages used with electric a c t u ators are only compat i ble with stem-up open b o d i e s. Sizes range from 1/2" to 6" pipe size or 5/8" O. D. SAE 45º copper tube. Selecting the proper va l ve body re q u i res the fo l l owing dat a : Fluid type Fluid temperat u re Po rt size (C v r at i n g ) Selecting the proper port size re q u i res the fo l l owing dat a : Inlet pre s s u re Re q u i red fl ow rate in either GPM (liquid) or lbs/hr (steam). I f the customer is using on-off c o n t rol, just select the va l ve body with the largest port size in the requested pipe size. Remember the fo l l owing ru l e when sizing the va l ve for fl o ating or pro p o rt i o n a l c o n t rol. At least one-half o f the ava i l able pre s- s u re must drop across the va l ve body when the va l ve is fully open. An ove r s i zed va l ve body will result in very nonlinear control action. It is better to have too small of a va l ve body than too l a r ge of o n e. Please refer to the section on va l ve sizing ( pages 35 43) for complete dat a.

12 Three-Way Valve Bodies Introduction Va l ve bodies are ava i l able in thre e - w ay configuration as mixing and dive rting va l ve s. Sizes range f rom 1/2" to 6" pipe size or 5/8" O. D. SAE 45º copper tube. Selecting the proper va l ve body re q u i res the fo l l owing dat a : Fluid type Fluid temperat u re Po rt size (C v r at i n g ) Selecting the proper port size re q u i res the fo l l owing dat a : Inlet pre s s u re Re q u i red fl ow rate in either GPM (liquid) or lbs/hr (steam). I f the customer is using on-off c o n t rol, just select the va l ve body with the largest port size in the requested pipe size. Remember the fo l l ow i n g rule when sizing the va l ve for pro p o rtional contro l. At least one-half o f the ava i l able pre s s u re must d rop across the va l ve body when the va l ve is fully open. An ove r s i zed va l ve body will result in ve r y nonlinear control action. It is better to have too small of a va l ve body than too large of o n e. Please refer to the section on va l ve sizing (page 35 43) fo r complete dat a.

16 Valve Actuators The three classes of a c t u ators that are suitable for use on our va l ves are linear stro ke hydraulic a c t u at o r s, linear stro ke electric actuators and rotary stro ke electric actuat o r s. Linear Stroke Hydraulic Actuators Linear stro ke hydraulic actuators such as the model EA81 are an excellent choice for smaller size va l ve s, up to 2 inch e s. They can be applied to either stem-up open or stem-up closed va l ve bodies. The spring loading sets the va l ve to the stem-up position. Linear Stroke Electric Actuators Linear stro ke electric actuators such as our CE ap p roved MF series mount dire c t ly on the va l ve b o dy. No linkage is re q u i red for va l ves of 2 inch or smaller size. These are fl o ating control units that stay in position when power is re m oved. The MF can be conve rted to full pro p o rtional control with the addition of a plug-in analog input board. Linear stroke hydraulic actuator Linear stroke electric actuator Rotary Stroke Box Style Actuators Rotary stro ke actuators such as our cul ap p roved EA series box style units are the most common fo rm used for va l ve s. The rotary action is conve rted to a linear s t ro ke by the linkage kit. Only actuators with a 180 s t ro ke can be used. These actuators must be coupled to a stem-up open va l ve body. Attempting to use these with stem-up closed va l ve bodies will result in phy s i- cal damage. Rotary stroke box style actuators 3-1 7

17 VALVES Valve Actuators Selection of Actuator The actuators in the selection table below may be used on va l ve assembl i e s. For details on the actuat o r s p e c i f i c at i o n s, consult the actuator section of t h i s c at a l og All actuators may be ord e red as components and assembled to the va l ve body component using the ap p ro p r i ate linkage kit component. Howeve r, a c t u ators with a three-digit Actuator code below may also be ord e red as complete va l ve assembl i e s. Th o s e a c t u ators are identified as part of an ava i l able fa c t o- ry assembly by using the (1) three digit Actuator code in place of the 000 and (2) the Control Fo rm code for an assembled va l ve in place of the VB (va l ve b o dy only) code in the complete va l ve assembly model code. In the table the Control Fo rm defines the kind of c o n t rol action the actuator will exe c u t e. Other than VB, this Control Fo rm will only ever appear in the va l ve model code in the case of complete factory va l ve a s s e m bl i e s. The table also provides important specifications to help select the correct actuator for an ap p l i c at i o n. These specifications include actuator torque (in-lb) or fo rce (lb) and travel time in sec. A c t u ators may use diff e rent linkage kits, depending on the va l ve body to wh i ch the actuator is coupled. Th e ava i l able linkage kits for a particular combination of va l ve body and actuator is defined in the Va l ve A s s e m bly Tables commencing on page ACTUATOR SELECTION TABLE ACTUATOR SPRING CONTROL ACTUATOR TORQUE IN-LB TRAVEL FORM CODE (FORCE LB) TIME (SEC) EA12 (N.O.)

25 VALVES Linkage Kits Most Actuators re q u i re linkage kits to couple them to the va l ve bodies. This is part i c u l a rly true of the box style actuat o r s. Selecting the proper linkage kit is critical to ensure proper operation. Physical damage to the va l ve may occur with the wrong linkage. All l i n k age kits are mounted in any upright position with the actuator ab ove the centerline of the va l ve body. AV-39X Series The AV die cast aluminum linkage with indication is intended for actuat o r s with 50 to 60 in-lb of ava i l able torque. Use it with EA12, E A 4 2 / E A A, E A 4 4 / E A A, EA52/EA52-A, and EA54/EA54-A on va l ve bodies of 2" or s m a l l e r. The AV-395 will mount these actuators to 2-1/2" through 4" va l ve s. Th e AV is intended for use with actuators with 220- in-lb of ava i l able torque. It can be used with models EA31, EA56/EA56-A and EA58/EA58-A on va l ve bodies of 2" or smaller. The model AV-396 will mount these actuators to 2-1/2" through 4" va l ve s. All AV- 3 9 X l i n k ages may be field assembled for NO or NC operation by setting cams. AV-352 The AV-352 is a unique linkage for gear train actuators that provides a mechanical adva n t age to more than double the cl o s e - o ff p re s s u re rating of s o m e va l ve assembl i e s. It can be used with 220 in-lb actuators to double cl o s e - o ff p re s s u re rating for 2-1/2" through 4" va l ve bodies and at rat e d p re s s u re for 5" and 6" va l ve b o d i e s. Use it with the EA31, EA56/ EA56-A, and EA58/ EA58-A actuat o r s. AV-358 The AV-358 linkage for electric a c t u ators is for use with the EA76/EA76-A actuators on 5" and 6" va l ve bodies. AV-611 The AV-611 linkage may be used to couple the EA81 hydraulic actuator to 1/2" t h rough 1-1/4" va l ve bodies. When using the AV in steam ap p l i c ations only, mount the actuator ab ove the va l ve body at 45 from ve rtical. In hot wat e r ap p l i c at i o n s, mount the a c t u ator ab ove the cent e rline of the va l ve body AV-672 The AV-672 linkage couples the MF series of e l e c- tric actuators to 2-1/2" t h rough 4 va l ve bodies.

Mixing and dive rt i n g va l ves are nominally linear. Sep a r ate curves shown fo r A or B ports are not dire c t ly additive. Total fl ow with both ports contributing is rated C V. T wo - w ay va l ves with brass trim are nominally equal p e rc e n t age in the composition disc types and norm a l ly used for water and low pre s s u re steam. T wo - w ay va l ves with stainless trim are nominally linear in the TFE and metal-to-metal disc types, and norm a l ly used for higher temperat u re water and steam.

35 VALVES Guidelines Valve Packing Life Va l ve packings are designed to provide many years of useful life befo re they must be rep l a c e d. The actual life, under the standard specified cond i t i o n s, will vary depending on the fre q u e n cy of va l ve cycle and the condition of the fluid cont rolled. The more fre q u e n t ly the va l ve is cycl e d and the more contaminated the fluid is with dirt and harsh ch e m i c a l s, the shorter the life of t h e p a ck i n g Water System Guidelines All heating and cooling systems are suscep t i ble to va l ve and system pro blems caused by impro p e r w ater tre atment and system storage pro bl e m s. These guidelines are provided to help avoid va l ve and water system pro blems from impro p e rly t re ated water or storage pro c e d u res in cooling and hot water systems in cooling and hot wat e r s y s t e m s, and to obtain maximum life from the va l ve s. While all cooling and heating systems are s u s c ep t i ble to pro bl e m s, closed chilled water syst e m s, including those containing brine or glyc o l, a re especially prone to system and va l ve pro b- l e m s. The best way to avoid pro blems is to fo l l ow the advice of a professional water tre atment and c o n t rol specialist. Leak Preve n t i o n. D u r ability of va l ve stems and packing is dependent on maintaining nond a m aging water conditions. Inadequate wat e r t re atment or filtration, not in accordance with the re c o m m e n d ations of a qualified water tre atment specialist or the ASHRAE handbook, can result in corrosion, scaling, or ab r a s ive part i cl e fo rm ation. Scale and corrosion products can m i gr ate from pipe walls to control va l ve s, re s u l t- ing in stem and packing scrat ch e s, and can a dve r s e ly affect packing life and other parts of the hyd ronic system. This condition can be avoided by the use of p roper cleaning, tre at m e n t ch e m i c a l s, and storage pro c e d u re s. To maintain non-damaging conditions, the system should be cleaned prior to start - u p. Filtration equipment should be used wh e re needed, and reg u l a rly s cheduled program of w ater condition monitoring and/or tre atment should be fo l l owe d. C o n t rol va l ve operation should be stable and not hunt at any time. Exc e s s ive stroking of the va l ve stem due to improper system setup can result in prem at u re we a r. C l e a n i n g. N ew systems usually contain dirt, solder flux, and weld and pipe scale. Th o rough fl u s h i n g with a 1% to 2% solution of trisodium phosphat e and rinsing is re c o m m e n d e d. Wet Storage. I f the system is stored wet, it should be completely filled with pro p e rly tre ated water and i s o l ated to avoid slow leaks wh i ch can contribute to serious corrosion pro bl e m s. Dry Storage. If drained, the system should be air dried, sealed, and tre ated with a desiccant to preve n t atmospheric corrosion of pipes a major source of pipe scale. Pipe scale is dried rust wh i ch will slough o ff the pipe walls as ab r a s ive part i cles and migr at e t h rough the system. S t rainers and Filters. Many closed systems have s l ow leaks or seep age, resulting in water loss without part i c u l ate re m oval. Consequently, part i c u l at e solids often build up in those systems, resulting in d ep o s i t s. In open systems like cooling towe r s, part i c- u l ate solid build-up is not as common because cont i nuous bl owd own is used to re m ove solids from the s y s t e m. Side stream filtration is often needed in closed systems because there is no regular bl owd own to re m ove pipe scale, sand, grit, and other ab r a s ive or s t i cky part i c u l ate mat t e r. Abrasive part i cles must not be allowed to circ u l ate through the system. To determine whether a filtration system is re q u i red, perfo rm a visual inspection of the wat e r. Flush a line with turbulence to assure that a rep re

36 Guidelines s e n t at ive water sample is collected and observe the t u r b i d i t y. Let the water settle for five minutes and inspect for part i c u l ate that has dropped out. I f chip scale and part i c u l ate are found in circ u l a- tion, install some type of f i l t r ation device such as a Y strainer, a cart r i d ge filter, and automatic backwashing side stream sand filter, or a chemical pot feeder packed with ch e e s e cloth that can be rep l a c e d p e r i o d i c a l ly. Backwashing sand filters (sized at 1% to 3% of system circ u l ation rate) are often a good choice because they are simple, inexpensive, and e ff e c t ive. Lines carrying water to and from the filtration system should be sized for high fl ow rates to make s u re the part i c u l ate matter is carried into the filtration system. F i l t r ation is often necessary when chemical tre atment is started in a system wh i ch has not prev i o u s- ly been ch e m i c a l ly tre ated. The tre atment often disl o d ges old deposits wh i ch then migr ate to heat e xch a n gers and va l ves unless re m oved by filtrat i o n. B e fo re installing a sophisticated filtration system, m a ke sure strainer baskets are emptied reg u l a rly. Also make sure the baskets have not been perm a- n e n t ly re m oved a common practice when they fill up quick ly and too much wo rk is re q u i red to ke ep them cl e a n. B e fo re installing filters or strainers in systems containing glycol, consult the glycol vendor for pro p e r t y p e. Chemical Water Tr e atment. I f the make - u p w ater hardness is gre ater than 300 ppm as calcium c a r b o n at e, the water should be softened or a tre atment should be used that contains a polymeric dispersant material wh i ch fo rms a soft sludge instead o f a l l owing the fo rm ation of h a rd scales. M a ke-up water iron should be less than 1.0 ppm. M a n ganese should be less than ppm (0.05 ppm if the system has significant leakage). If not, an iro n / m a n ganese re m oval system or a n ew water source should be used. Water tre atment control addresses four pro bl e m a reas: corrosion, scale, deposition, and bacteria. For control, a nitrite or moly b d ate based progr a m is typically used in conjunction with testing and m o n i t o r i n g. The corrosion control program most commonly used is 600 to 1220 ppm sodium nitrite or 100 to 300 ppm moly b d at e, at a ph of 9.5 to Incl u d e a copper corrosion inhibitor such as To ly t r i a z o l ( T TA) or Benzotriazole (BZT) since uncontro l l e d copper corrosion can lead to corrosion of s t e e l. Note The addition of g lycol, especially automot ive antifre eze, does not assure corrosion pro t e c- tion. Refer to the manu fa c t u re r s literat u re fo r specific re q u i re m e n t s, including concentrat i o n s and materials of c o n s t ru c t i o n. C o n t rol of bacteria is important because bacteria can break down the nitrites. The level of b a c t e r i a should be kept at less than 10,000 CFUs (colony fo rming units) per ml of w at e r. Fo l l ow your supp l i e r s instructions for bacterial contro l. O p e r ate your chemical tre atment program within the guidelines set by your water tre atment supplie r. Monitor results monthly, sw i t ching to we e k ly i f p ro blem resolution is necessary. Control Loop Operat i o n. Va l ves should not be ove r s i zed.

A. Two-Position Valves T wo-position va l ves are norm a l ly selected line size to ke ep pre s s u re drop at a minimum. The diff e re n t i a l p re s s u re in psi should be no more than 10% of ava i l- able inlet pre s s u re in psia. B. Proportional Two-Way Valves These are usually selected to take a pre s s u re dro p equal to at least 50% of the ava i l able pre s s u re ( i. e., the pump pre s s u re diff e rential ava i l able betwe e n s u p p ly and re t u rn mains with design fl ow at the va l ve l o c ation). As ava i l able pre s s u re is often difficult to c a l c u l at e, the normal pro c e d u re is to select the va l ve using a pre s s u re drop at least equal to the drop in the coil or other load being controlled (exc ept wh e re small booster pumps are used), but never less than 5 psi (34 k Pa ). When design temperat u re drop is less than 60ºF (33ºC) for conventional heating systems, higher pre s s u re d rops across the va l ve are needed for good contro l re s u l t s.

Secondary Circuits with Small Booster Pumps 50% of Ava i l able Pre s s u re Diff e rence (Equal to drop t h rough load, or 50% of booster pump head) C. Proportional Three-Way Valves Recommended Pre s s u re Drop - Bypass Ap p l i c at i o n : 50% of ava i l able pre s s u re, or equal to pre s s u re d rop through the load at full fl ow. Th re e - w ay va l ves in the re t u rn used to control heat output by throttling water fl ow to the load (by p a s s ap p l i c ations) are controlling output in the same manner as throttling two - w ay va l ve s, and must be selected using the same high pre s s u re drops if good contro l results are to be obtained. Recommended Pre s s u re Drop - Constant Fl ow Ap p l i c ations: 20% of ava i l able pre s s u re, or equal to 1/4 of the pre s s u re drop through the load at full fl ow. Th re e - w ay va l ves used with individual pumps to c o n t rol heat output by varying water temperat u re to the load (constant fl ow ap p l i c ations) are controlling output by mixing two water sources at diff e rent t e m p e r at u re s, and do not re q u i re high pre s s u re d rops for good control re s u l t s

38 Valve Sizing Information For Water In most cases the re q u i red C V falls between two va l ve s i ze s. If the pre s s u re drop of the smaller is accep t- able for the ap p l i c ation, select the smaller va l ve. CAVITATION LIMITATIONS ON VALVE PRES- SURE DROP A va l ve selected with too high a pre s s u re drop can cause erosion of discs and/or wire drawing of t h e s e at. In addition, cav i t ation can cause noise, damage to the va l ve trim (and possibly the body) and ch o ke the fl ow through the va l ve. Do not exceed the maximum diff e rential pre s s u re ( p re s s u re drop) for the va l ve selected. The fo l l owing fo rmula can be used on higher temperat u re water systems, wh e re cav i t ation could be a p ro blem, to estimate the maximum allow able pre s- s u re drop across the va l ve : Pm = 0.5 (P1 - Pv) Pm = Maximum allow able pre s s u re dro p P1 = Absolute inlet pre s s u re (psia) Pv = Absolute vapor pre s s u re (refer to Vapor P re s s u re of Water Table or Steam Tabl e ) Note: Add 14.7 psi to ga u ge supply pre s s u re to obtain absolute pre s s u re va l u e. For example, if a va l ve is controlling 200ºF water at an inlet pre s s u re of 18 psig, the maximum pre s s u re d rop allow able would be: Pm = 0.5 [( ) ] = 10.6 psi ( Vapor pre s s u re of 200ºF water is psi) I f the pre s s u re drop for this va l ve is less than 10.6 psi, cav i t ation should not be a pro bl e m. Systems wh e re cav i t ation is shown to be a pro bl e m can sometimes be redesigned to provide lower inlet ve l o c i t i e s. Va l ves having harder seat materials should be furnished if inlet velocities cannot be lowe re d.

Two Position Zone Valves and Direct Radiator Valves Use a minimum of 10% of inlet pre s s u re (psig). B.Proportional Control Valves Other fo rms of the fo rmula are : Q = 3C V P x P 2 K P = ( QK )2 x 1 3 C V P 2 P 2 = ( QK )2 x 1 3 C V P 2 L ow pre s s u re (15 psig or less): of 80% of ga u ge inlet p re s s u re. When C V re q u i red is between two va l ve sizes and closer to the smaller va l ve size, re - s i ze for C V u s i n g 42% of the absolute inlet pre s s u re as pre s s u re dro p. Use the va l ve that is larger than the calculated C V. For steam pre s s u res gre ater than 15 psig: 42% of the absolute inlet pre s s u re. When C V re q u i red is between two va l ve size s, select the larger size. Note: K norm a l ly is 1 (K = 1 for sat u r ated steam). These fo rmulas can be used to calculate one of the quantities if the others are know. Fl ow coefficients (C V s) for specific va l ve bodies a re given on specification pages of this cat a l og. Note: Do not size steam va l ves on higher system p re s s u res using a pre s s u re drop gre ater than 42% o f the absolute inlet pre s s u re. C V (FLOW COEFFICIENT) DETERMINATION The Steam Capacity Tables or Slide Rule (refer to this and the fo l l owing two pages) is based on the fo l l owing fo rm u l a : C V = QK 3 P x P 2 W h e re: C V = Coefficient of fl ow Q = Lbs per hour of s t e a m P = Diff e rential pre s s u re in psi ( p re s s u re dro p ) P 2 = Outlet pre s s u re in psia (ab s o l u t e ) psig = psia (ab s o l u t e ) K = 1 + ( x ºF super- h e at ) Note: K norm a l ly is 1 (K = 1 for sat u r ated steam)
