Technical Data Dimensions and Weights Booster Pump Control Valve Model 740Q Quick Active Check Valve WW-740Q ■ Isolates system from the effects of pump 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 ❑ Solitary single speed pumps ❑ Battery of single speed pumps (add & switch) Data is for Y-pattern, flat disk valves For more flow charts, refer to Engineering Section Main Valve Surge Anticipating Control Valve Model 735-M Booster Pump Control Valve In this system, a pump battery supplies the main line through a manifold. The Model 740Q, installed downstream from each pump: ■ Prevents surge generation rather than minimizing surge damage ■ Provides surge free starting and stopping of supplementary pumps ■ Allows surge free switching between “on-duty” pumps ■ Delays reaction of variable speed primary pump to single speed supplementary pump going on line or off line.

BERMAD Irrigation WW-700 Series Sequence of Operation (Normally-Open Type) BERMAD Irrigation WW-700 Series Sequence of Operation (Normally Closed Type) The Model 740Q is a solenoid controlled valve equipped with a limit switch, a 3-Way solenoid pilot and check valves. For large valves, an accelerator quickens valve response. Prior to pump start, the valve is hydraulically closed although electrically open. Even though the de-energized solenoid [1] vents the upper control chamber [2], it remains full as no opening hydraulic forces are applied. Pump start command is issued to the BR740-E electronic...
