Technical Data Dimensions and Weights Booster Pump Control Valve Model 740 WW-735-M ■ Eliminates surge in all pumping systems: ❑ Booster & deep well, single & variable speed ■ Eliminates surge in all distribution networks: ❑ Municipal, high-rise buildings, sewage, HVAC, irrigation ❑ Difficult to maintain, remote locations, and older systems Data is for Y-pattern, flat disk valves For more flow charts, refer to Engineering Section Pilot Valve Selection Main Valve Surge Anticipating Control Valve Model 735-M Data is for Y-pattern, flanged, PN16 valves Weight is for PN16 basic valves “C” enables removing the actuator in one unit “L”, ISO standard lengths available For more dimensions and weights tables, refer to Engineering Section Relief Line Surge Anticipating Control Valve In this system, a pump battery supplies the main line through a manifold. The Model 735-M: ■ Eliminates surge upon power failure ■ Provides surge free switching between “on-duty” pumps ■ Closes smoothly according to pilot setting Typical Applications Control System Valve Patterns: “Y” (globe) & angle Size Range: 11/2–32” (40-800 mm) End Connections (Pressure Ratings): Flanged: ISO PN16, PN25 (ANSI Class 150, 300) Threaded: BSP or NPT Others: Available on request Working Temperature: Water up to 80°C (180°F) Standard Materials: Body & Actuator: Ductile Iron Internals: Stainless Steel, Bronze & coated Steel Diaphragm: NBR Nylon fabric-reinforced Seals: NBR Coating: Fusion Bonded Epoxy, RAL 5005 (Blue) NSF & WRAS approved or Electrostatic Polyester Powder, RAL 6017 (Green) Standard Materials: Accessories: Bronze, Brass, Stainless Steel & NBR Tubing: Copper or Stainless Steel Fittings: Forged Brass or Stainless Steel Pilot Standard Materials: Body: Brass, Bronze or Stainless Steel Elastomers: NBR Springs: Galvanized Steel or Stainless Steel Internals: Stainless Steel Valve Size The Model 735-M Surge Anticipating Valve is an off-line, hydraulically operated, diaphragm actuated valve. The valve, sensing line pressure, opens in response to the pressure drop associated with abrupt pump stoppage. The pre-opened valve dissipates the returning high pressure wave, eliminating the surge. The Model 735-M smoothly closes drip tight as quickly as the relief feature allows, while preventing closing surge. The valve also relieves excessive system pressure.
