08.16 Balancing Valves

Transcription

1 08. Tour & ndersson calibrated balancing valves offer a reliable, simple and cost effective way to measure and balance all flow rates. Full throttling range is achieved by, 8,,, 0 or full turns of the handwheel, enabling a precise setting. This high degree of accurate adjustment means that the system can be balanced precisely. The actual pressure drops in heating and cooling systems are difficult to establish by calculation because water flows vary from design flows. They can be corrected easily by regulating the desired water flow with Tour & ndersson globe style balancing valves. y measuring the pressure drop across measuring ports at a particular handwheel setting, the water flow for the valve size can be read easily from the appropriate pressure drop graph or flow balancing wheel. If the flow does not conform with that specified, adjust the valve and repeat the measuring procedure until the correct flow has been obtained. NOTE: ll Tour & ndersson balancing valves include a concealed memory feature with a locking tamper-proof setting. Series 8K and T Series 8 and 8 valves have an metal body. metal is a copper alloy that eliminates the added expense of dielectric fittings. T Series 88 and 89 balancing valves have ductile iron bodies and metal or ductile iron trim, depending on size. Test ports feature self-sealing construction for insertion-type pressure or temperature probes. ll valves are rated from F/0 C to +0 F/+0 C. Service will also be governed by the connecting coupling gasket ratings for grooved and flanged valves. Insulation kits are available for / "/ 0 sizes for Series 8K and T Series 8, 8, 88 and 89 balancing valves. T alancing valves provided by Victaulic can be ordered individually or as a component of the Series 99 or 9V KOIL-KIT Coil Pack. See the Series 99/9V Contractor Order Form () on page 9 of publication 08.0 for help ordering your Victaulic KOIL- KIT Coil Pack. Victaulic KOIL-KIT Coil Packs provide a simplified, quality coil installation while ensuring optimal hydronic systems design requirements are met. The Series 99/9V is suitable for a variety of hot and cold water applications including treated and untreated water systems. The Victaulic KOIL-KIT Coil Pack consists of the following components: Series 8Y Y-Strainer/all Valve or Series 8T all Valve Union Combination, two Coil Hoses, a Series 8U Union Port Fitting and a T balancing valve. There are two options when ordering a Victaulic KOIL-KIT Coil Pack: Series 99 KOIL-KIT Coil Pack or Series 9V KOIL-KIT Coil Pack with TC Valve. The Series 99 and Series 9V comes standard with the components listed above. dditionally, the Series 9V includes the option to have the TC valve of your choosing assembled and shipped with the Victaulic KOIL-KIT Coil Pack. Please note that when ordering a Series 9V, Victaulic offers one balancing valve, the Series 8K. Specify either Series 99 or Series 9V when ordering. For added convenience, when coil hoses are ordered as a component of the Series 99 or 9V KOIL-KIT Coil Pack, all hoses can be provided pre-connected to the Series 8Y or 8T on the supply side and the Series 8U on the return side (specify connection preference when ordering).

13 08. CORRECTION FCTORS For liquids other than water, the flow values from the balancing wheel can be adjusted as follows: Divide the flow rate (as indicated by the balancing wheel) by the square root of the specific gravity. ctual Flow = q CI SG This applies to liquids having, on the whole, the same viscosity as water, i.e. most water/glycol mixtures and water/brine solutions at room temperature. t low temperatures, the viscosity increases and laminar flow may occur in certain valves. The risk increases with small valves, low settings and low differential pressures. computer program (T-Select) is available for calculation of pre-setting values and other applications. When the flow setting is verified or changed to the final setting, the memory stop should be set. Contact Victaulic for further information. SIZING LNCING VLVE When p and the design flow rate are known, use the formula shown to calculate the C V value or use the graphs on page 8. The Tour & ndersson balancing wheel can also be used. computer program, T-Select, is available from Victaulic for calculation of pre-setting values and other applications.
