AP cylinder piston actuators
SAP actuator is a kind of double function piston cylinder actuators. Supply pressure is greater than its thin air pressure, the actuator is larger, usually use power output voltage regulator, such as in the actuator is proportional control, need to take dual role of pneumatic valves locator.
