For operation of rising stem type valves

Product Features

• Hydraulic piston generates dependable and efficient thrust which acts directly on the valve stem
• Smooth linear motion, even at rapid operating speeds
• Actuator is mounted directly on the valve
• Piston threaded directly to the valve stem for installation on new or in-service valves
• Actuator absorbs all end-of-stroke thrust to protect the valve
• Operating speed is easily controlled
• Actuator is hydraulically locked in position
