Data sheet Solenoid valve s EVR 2 - EVR 40 EVR is a direct or servo operated solenoid valve for liquid, suction, and hot gas lines with HCFC and HFC refrigerants. EVR valves are supplied complete or as separate components, i.e. valve body, coil and flanges, if required, can be ordered separately. Features y A complete range of solenoid valves for refrigeration, freezing and air conditioning systems y Normally closed () and normally open (NO) versions available y AC and DC coils are interchangeable on all valve body versions y Use with any fluorinated refrigerant y Designed for media temperatures up to 220 F y Flare connections up to in y Solder connections up to 2 in y Solder versions have extended connections; there is no need to dismantle the valve when soldering Approvals UL listed, file MH 648 Note: These approvals are only recognized when one of the EVR series of solenoid valves found in this leaflet is combined with a GP general purpose coil.

Valve selection example Note: When selecting the appropriate solenoid valve, it is easier to convert the actual required capacity to that of the rated capacities listed in the tables. Liquid line solenoid valve selection example Refrigerant R4a Condensing temperature t c = 00 F Liquid temperature ahead of valve t l = 90 F Maximum allowable pressure drop across valve Δp = 2 psi Evaporator capacity Q o = 0 TR (required valve capacity) The table capacity should be corrected by the corresponding factor as: Qtable x fliquid = Qo Step : Determine the correction factor for liquid temperature. From the correction factor table found on page 8, a liquid temperature of 90 F corresponds to a factor of.0. Step 2: Correct the required valve capacity. This is done by dividing the evaporator capacity by the liquid correction factor. Q corrected = 0/.0 = 9. TR Step : Select the appropriate capacity table and choose the first valve whose capacity is greater than or equal to Q corrected at the required pressure drop. Using the R4a liquid capacity table found on page 8, the EVR is selected as it has a capacity of 2. TR at a Δp = 2 psi. This is done by utilizing various correction factors in the selection process. The following examples illustrate how this is done. Suction line solenoid valve selection example Refrigerant R4a Liquid temperature ahead of expansion valve t l = 90 F Evaporator temperature t e = 0 F Superheat ahead of valve t s = F Maximum allowable pressure drop across valve Δp = psi Evaporator capacity Q o = 0 TR (required valve capacity) The table capacity should be corrected by the corresponding factor as: Qtable x fliquid x fsuperheat = Qo Step : Determine the correction factor for superheat ahead of the valve by increasing the required valve capacity by 2% for each 0 F of actual superheat above the table rated value of F. In the example. a superheat of F corresponds to a 0 F increase above the table value which is equivalent to a superheat correction factor of 0.98. Step 2: Determine the correction factor for liquid temperature. From the correction factor table found on page, a liquid temperature of 90 F corresponds to a factor of.0. Step : Correct the required valve capacity. This is done by first multiplying the evaporator capacity by the superheat correction factor and then dividing it by the liquid correction factor. Q corrected = 0/0.98/.0=9. Step 4: Select the appropriate capacity table and choose the first valve whose capacity is greater than or equal to Q corrected at the required evaporating temperature and pressure drop. Using the R4a suction vapor capacity table found on page, the EVR 40 is selected as it has a capacity of 4. TR at t e = 0 F and Δp = psi. 6 DKRCC.PD.BB0.A9.22
Valve selection example (continued) Hot gas line solenoid valve selection example With hot gas defrost, pressure in the evaporator quickly rises to a value near that of the condensing pressure and remains there until the defrost cycle has been completed. Therefore. when selecting valves for hot gas applications, sizing is based primarily on the condensing temperature t c and the pressure drop D p across the valve. Example (with heat recovery) Refrigerant: R4a Evaporator temperature: t e = 0 F Condensing temperature: t c = 00 F Hot gas temperature ahead of valve: t h = 80 F Maximum allowable pressure drop across valve: Δp = psi Output of heat recovery condenser: Q h = TR (required valve capacity) The table capacity should be corrected by the correspondig factor as: Qtable x fevaporator x fsuperheat = Qo Step : Determine the correction factor for hot gas temperature (t h = t c + 40 F) by increasing the required valve capacity by % for each 0 F of actual superheat above the table rated superheat value of 40 F. In the example, an actual hot gas temperature of 80 F is 40 F higher than the calculated table value of (t h = t c + 40 F = 40 F). This is equivalent to a hot gas correction factor of 0.96. Step 2: Determine the correction factor for evaporator temperature. From the correction factor table found on page 9 an evaporator temperature of 0 F corresponds to a factor of.09. Step : Correct the required valve capacity. This is done by first multiplying the heat recovery capacity by the hot gas correction factor and then dividing it by the evaporator correction factor. Q corrected = /0.96/.09=4. Step 4: Select the appropriate capacity table and choose the first valve whose capacity is greater than or equal to Q corrected at the required condensing temperature and pressure drop. Using the R4a hot gas capacity table found on pages 9 and 20, the EVR 2 is selected as it has a capacity of 2.8 TR at t c = 00 F and Δp = psi. DKRCC.PD.BB0.A9.22

Servo operation : Direct operation EVR 2 and EVR are direct operated. The valves opens to admit full flow when the armature (6) is moved up into the magnetic field of the coil. The valves operates with a minimum differential pressure of 0 psi. The valve plate (8) is fitted directly to the armature (6). Inlet pressure and spring force act to close the valve when the coil is de-energized. 2a: EVR 4 EVR 22 are servo-operated with a floating diaphragm (80). The pilot orifice (29) is located in the center of the diaphragm. The pilot valve plate (8) is fitted directly to the armature (6). When the coil is de-energized, the valve port and pilot orifice are closed and the inlet pressure acts both above and below the diaphragm. The valve port and pilot orifice are kept closed by the armature spring force and the differential pressure between inlet and outlet sides. When current is applied to the coil, the armature is pulled up into the magnetic field and the pilot orifice opens. This relieves pressure above the diaphragm because the space above it becomes connected to the outlet side of the valve. The differential pressure between inlet and outlet presses the diaphragm away from the valve seat (8) and the valve opens to admit full flow. A minimum differential pressure (0. psi for EVR 4 EVR 22) is necessary to open the valve and keep it open. When the coil is de-energized, the pilot orifice closes. Then. via the equalizing port () the pressure above the diaphragm rises to the same value as the inlet pressure, which results in the valve port being closed by the diaphragm. EVR 6 EVR, NO, function in a manner opposite to the valves; they are open when the coil is de-energized. Normally open (NO) EVR valves are available with servo operation only. 8 DKRCC.PD.BB0.A9.22

EVR 2 and EVR 40 are servo-operated piston valves. The valves are closed when the coil is de-energized. In operation. EVR 2 is the same as for EVR 4 EVR 22. but the design is different. The pilot unit is located in the cover and the servo unit is a piston (80) with a cast iron piston ring. For EVR 2 EVR 40, piston (80) and valve plate (84) will close against the valve seat (8) due to the differential pressure between inlet and outlet plus the force from the return spring (6). When the coil is energized, the pilot orifice (29) is opened and pressure on the spring side of the piston is relieved. The pressure differential now opens the valve. The minimum differential required to keep the valve fully open is psi. DKRCC.PD.BB0.A9.22 9
