Rotary Vane Actuator Uses & Applications

Rotary vane actuators control the opening and closing of valves via precisely applied hydraulic force. The actuator consists of opposing chambers connected by pressure equalizing passages located in the lower and upper heads. This creates a constant torque output through the entire rotation of the valve. Rotary vane actuator applications include valve control on pipelines and numerous high-speed, high-vibration industrial processes.
