Rotary Vane Actuator

Only one moving part allows for a 50 year design life with minimal maintenance. Double vane design will not produce any side loading forces on the valve stem or actuator bearings. Balanced and constant torque is applied directly to the valve stem, without any internal power loss, throughout the complete stroke. The most compact and efficient actuator design available.

Rotary Piston Actuator

Hydraulic piston produces smooth thrust directly to the valve stem without shock or gearing losses. Easy installation and removal provides lower maintenance cost. Hydraulically locks in any desired position. Easily controlled operating speed or variable speed for wedge type gate valves.
