Introduction
Rotary pneumatic actuators, also known as pneumatic actuators or pneumatic devices, are actuators that use the pressure of compressed air to drive the opening and closing or regulating valves. They are mainly composed of cylinders, pistons, gear shafts, end covers, seals, screws, etc. composition. Pneumatic actuators are generally used with various types of valves, including opening degree indication, stroke limit, solenoid valves, positioners, pneumatic components, manual mechanisms, signal feedback and other components.

Pneumatic Actuator FAQ
Q1: Pneumatic Valve can’t Move ?
A1: Check the Solenoid Valve is normal or not;Test the actuator separately with air supply;Check the handle position.
Q2: Pneumatic Actuator with slow motion ?
A2: Check air supply is enough or not;Test the Actuator Torque is ok or not for the valve;Check Valve coil or other components are too tight or not;
Q3: Reply Devices without Signal ?
A3: Inspect and repair power circuit;Adjust the cam to correct position;Replace micro switches.
