Pneumatic Actuator

Types of Valve Actuators
Each type of actuator is designed for a particular type of valve. Valves can be sorted by their motion and their function.

Valve Motion
Rotary hydraulic valve actuators - Rotary actuators are used for rotary motion valves such as ball, plug, and butterfly valves through a quarter-turn or more from open to close. The closing element is generally a disc or ellipse which turns about an angular shaft. Rotary motion valves specifications include:

Actuator torque- Torque is the measure of force needed to produce rotary motion. It is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied.
Range of rotary motion- Common ranges of motion include 90° (quarter-turn), 180°, 270°, and 360° (multi-turn).
Linear hydraulic valve actuators - Linear actuators move linear valves such as gate, globe, diaphragm, and pinch valves by sliding a stem that controls the closure element. Linear motion valve specifications include:

Valve stem stroke length- Stroke is a term used to define the travel required by the valve from fully open to fully closed. The stroke of an actuated valve is determined by the actuator if the actuator selected has a stroke that is less than the stroke of the valve. Using an actuator with fewer strokes than the valve will "short stroke" the valve and the full CV rating of the valve will not be realized.
Actuator force or sealing thrust- The actuator must supply enough force to overcome the pressure in the system to close the closing element and keep it shut.
