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.

* Suggested maximum flow rate, however 25% higher flow rate is achievable

  • 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
