Manual Overrides

The JS-1 override is a single acting mechanism that will extend the actuator piston rod when operated. This override is intended for infrequent use.

The JS-2 override is capable of extending or retracting the actuator and can be engaged at any position from full open to full closed. Since the entire manual override mechanism is incorporated into the actuator adapter bracket it allows for removal or service of the power cylinder while maintaining complete control of the valve.

The HO-1 is a one way hydraulic override for use on spring return actuators. This override compresses the spring and operates the valve, the spring force is used to move the valve to the failure position.

The HO-2 override is used on double acting actuators and is capable of extending or retracting the actuator. The HO-2 also allows for very precise speed control by regulating the flow of the hydraulic fluid in the system.

Hydraulic Hand Pump

The “Hydraulic Hand Pump” utilizes the most current technology to provide an efficient back-up system for opening and closing valves when power gas is not available.
