Electric Control Actuator

Pump Control Valves protect pumps and pipelines against any damage that may result from start / stop or flow surging caused by an electrical trip out by minimizing the pressure surges (water hammer) by slowly increasing or decreasing the velocity of the water. An Electric Actuator provides precise PLC control over the valve position.

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
Can be maintained in line
High cavitation resistance due to poppet and cage design
Stainless steel and bronze internals with UHMWPE seals
Cast steel body (galvanised body optional)
Low pressure drop across valve
High sealing integrity and dirt tolerance
Flanges and face dimensions to customer specification
Closes to pre-open position if the electrical signal is lost
Manual override on actuator
Electric specifications to suit customer specifications
