Useful on high-pressure valves
Stroke an actuator or operate a valve in the absence of system control pressure.
Manual valve operation in absence of control pressure
The Cameron manual hold-open device is used to manually operate the valve when control pressure is not available. The device threads directly to the top of the actuator. Rotating the handwheelproduces enough torque to overcome the actuator spring force and mechanically open the valve.
A hydraulic boostershould be used on high-pressure valves or any instance where the surface safety valve (SSV) must be manually opened and the maximum torque of this device is exceeded. This is to be used as a hold-open device only.
Our manual hold-open device utilizes high-pitch threads on the stem screw and nut, which facilitates rapid operation. The device is easy to install or remove by simple hand rotation.
