Types of Valve Actuators - Assured Automation

A valve actuator is a mechanical device that uses a power source to operate a valve. This power source can be electric, pneumatic (compressed air), or hydraulic (the flow of oil). There are two main types of actuators, one for each of the two main types of valves that require them.

Valve actuator Wiki

A valve actuator is the mechanism for opening and closing a valve. Manually operated valves require someone in attendance to adjust them using a direct or geared mechanism attached to the valve stem. Power-operated actuators, using gas pressure, hydraulic pressure or electricity, allow a valve to be adjusted remotely, or allow rapid operation of large valves.

Selecting A Solenoid Valve For Operating A Shutoff

If you do not vent the actuator, it will not completely stroke the valve. You must also vent the pressure side of the piston(s) or diaphragm as the actuator is returning to its normal position. Modern rack & pinion actuators have universal "NAMUR" supply port configurations that allow the use of special direct mount solenoids to eliminate the need for tubing or fittings.
