Hydraulic Actuator Valve

Hydraulic Actuator Valve

Hydraulic Actuator is available in sizes from 1-13/16" thru 7-1/16" and pressure ratings of 2,000psi thru 15,000psi. The Actuator is designed with safety in mind and is adaptable to all major manufacturers’ gate valves. In addition, optional wire-cutting applications and fusible-opening devises are available.

The Actuator is designed to operate when hydraulic pressure is applied between a stationary cylinder tube and a moveable piston causing the down-stem, spring and flashboard to move downward, opening a reverse-eating gate valve. When hydraulic pressure is withdrawn or liquid is leaking, the helical spring returns the actuator to the fully closed position .This fail-safe return action occurs independently of valve pressurization. The actuator spring housing is a sealed unit which eliminates internal corrosion caused by atmospheric contamination, thereby:

  • Reducing down time
  • Reducing related maintenance and repairing time
  • Extending actuator life
