PUMP CONTROL VALVES
PURPOSE
HPE’s Pump Control Valves protect the pump against any damage that may result from starting / stopping, flow surging or an electrical trip out.
FEATURES
Isolates and throttles in the operating direction
Throttles and maintains the pump pressure when the downstream column is empty or partially full
Throttles the pump outlet when the pump is stopped to prevent water hammer
Operates with only one electrical signal to the solenoid
Closes to the pre-open position if the electrical signal to the solenoid or the pump motor is lost
SPECIFICATIONS
Conform to ANSI B16.34
Y-pattern globe-type body for reduced pressure drop
Can be maintained in line
Flanges to customer requirements
Cast steel body with corrosion resistant internal parts (galvanised body optional)
Rated 25 MPa working pressure
High dirt tolerance
High cavitation resistance due to poppet and cage design
