Transcription

1 Valves and Koil-Kit Components The 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, or 6 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 are frequently incorrect. 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. Insulation kits are available for / 6"/ sizes for Series 86, 8, 88 and 89 Valves. NOTE: ll Valves include a concealed memory feature with a locking tamper-proof setting. Series 8, 86, 8 and 8Y have an metal body. metal is a copper alloy that also eliminates the added expense of dielectric fittings. The Series 8U has a brass body. Series 88 and 89 have ductile iron bodies and metal or ductile iron trim, depending on size. Test points feature self-sealing construction for insertion-type pressure or temperature probes. ll valves are rated to + F/+ C and F/ C. Service will be governed by the connecting coupling gasket ratings for grooved and flanged valves. alancing Koil-Kit Hook-up Package TC Series 8/86/8 RETURN Series 8U COIL SUPPLY Series 8Y JO/OWNER CONTRCTOR ENGINEER System No. Submitted y Spec Sect Para Location Date pproved Date

13 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 volume by weight (specific density q). ctual Flow = q CI γ 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 III) 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 6 8.

16 Diagram SERIES 8/86/8 This graph shows the pressure drop across the pressure test points of the valve. straight line connecting the bars for flow rate, C V and pressure drop shows the relationship between these variables. The position for each valve size is arrived at by drawing a horizontal line from the C V value obtained. Example: Wanted: Pre-setting for a " valve at a desired flow rate of 6. and a pressure drop of ft. Solution: Draw straight line joining 6. and ft. This gives C V =.9. Now draw a horizontal line from C V =.9. This intersects the bar for a " valve at the desired pre-setting of. turns. NOTE: If the flow rate falls outside of the scale in the diagram, the reading can be made as follows: Starting with the example above, we get ft., C V =.9 and the flow rate 6.. t ft. and C V =.9 we get the flow rate.6.
