OIL HYDRAULIC ACTUATED
VALVE

The Hydrocore oil-hydraulic actuated valve is used for remote isolating of pipeline applications and mainly used in: Industrial Water Systems, Municipal Water Supply Systems, Pump Stations, Mine Water Reticulation and Petrochemical Plants 

Once an electrical signal is given, the solenoid valve switches over, hydraulic fluid enters the cylinder opening compartment and pulls the valves shuttle towards the open position. Once power is removed the solenoid valve switches to the original position, hydraulic fluid enters the cylinder closing compartment and pushes the valve shuttle to the closed position. In the event of a power failure, the power pack’s accumulator, provides enough oil pressure and oil volume to close the valve. The open and closing speeds can be set separately to prevent water hammer when the valve closes.

FEATURES
  • Does not need a gearbox to operate

  • Superior flow coefficient (Cv/Kv)

  • 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 design

  • Stainless steel moving internals parts

  • Cast steel body 

  • Low pressure drop across valve

  • Flanges and face-to-face dimensions to customer specification

  • Manual override on actuator

  • Electric specifications to suit customer specifications

  • No possibility of contaminating of the actuating fluid.
