Introduction
The Double Acting pneumatic actuator controls the valve by the gear shaft rotating movement, which is driven by the meshing movement of the rack and the gear by the piston.
When the pressure of the air source enters the middle cavity between the two pistons of the cylinder from the air port, the two pistons are separated and moved toward the two ends of the cylinder, and the air in the air chambers at both ends is discharged through the air port, and the two piston racks simultaneously drive the output shaft (gear) Turn counterclockwise. Conversely, when the pressure of the air source enters the air chambers at both ends of the cylinder from the air port, the two pistons are moved toward the middle of the cylinder, and the air in the middle air chamber is discharged through the air port. At the same time, the two piston racks synchronously drive the output shaft to rotate clockwise.
Features
A. CE certificate and According with international Standards, such as NAMUR,ISO5211 and DIN.
B. Integrated Design with Stable Quality.
C. Dual Piston rack and Pinion Design with High Output Power.
D. Multi-position Indicator, On-site Visual Instruction.
E. The switching actions are driven by the air source, and can be moved back and forth by the gas: ventilation is on, ventilation is off, and the gas is held in place when the gas is off;
F. Double-acting pneumatic actuator refers to a cylinder that can input compressed air to the two chambers to achieve two-way movement.

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.
