Valve actuators are devices mounted on a valve that, in response to a signal, automatically moves the valve to the desired position using an outside power source. The power source may be pneumatic, electrical, or hydraulic.
Pneumatic valve actuators, aluminum pneumatic valve actuators, convert air pressure into motion.
A manual actuator are actuators that requires no outside power source. Handwheels, chainwheels, and levers are examples of manual actuators.
Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion.
Electric motor actuators mount on valves that, in response to a signal, automatically move to a desired position using an outside power source. A single or three phase AC motor or DC motor is utilized to drive a combination of gears to generate the desired torque level.
