Product details
AT series pneumatic actuator
AT series pneumatic actuatorOur factory has introduced advanced Italian technology and independently developed and produced it. And conduct comprehensive testing on the product through a professional pneumatic valve testing center. It is powered by compressed air and converts the air pressure inside the cylinder into a torque of 0 ° -180 ° through gear piston transmission. Can be applied to various types of rotary angle stroke valves, such asPneumatic ball valve、pneumatic butterfly valve、Pneumatic globe valve、Pneumatic gate valvePneumatic plug valves, etc. The AT series compact pneumatic actuator mechanism is designed to be simple and compact, with a unique style, fully sealed, and has an internal air path that is economical and does not require exposed connecting pipelines to prevent damage. Using the ISO5211 connection standard is extremely convenient for installing solenoid valves, signal feedback devices, valve positioners, or other accessories. The design takes into account safe operation, ease of maintenance, and ease of disassembly and assembly.
AT pneumatic actuatorThe shell is extruded and drawn from aluminum alloy, with sandblasted surface and hard anodized oxidation treatment, which can prevent corrosion and wear. It has the advantages of light weight, beautiful appearance, strong strength, and reliable sealing. The piston guide ring of the alcohol aldehyde shaft gasket has very low friction resistance and can absorb the lateral thrust of the piston. The inner wall of the cylinder is polished to reduce overall motion friction, and an alcohol aldehyde bearing is installed at the bottom of the top of the output shaft to reduce rotational friction resistance and extend service life. The end cap and piston are precision formed by aluminum alloy die-casting, with good fracture resistance. The surface of the end cap is coated with high-strength epoxy resin paint, which is generally resistant to weak acids, weak bases, and cleaning agents. The output shaft is made of 45 # carbon steel and has undergone surface electroplating treatment. The opening indicator can visually display the position of "on" or "off", and is easy to remove for wrench operation. The travel adjustment screw can mechanically limit the rotation angle of the pneumatic actuator, and it adjusts the position of the pneumatic actuator on or off in a field manner. It can provide an adjustable range of ± 5 ° for standard products at both 0 ° and 90 ° positions. Ensure synchronization accuracy with the valve.
All pneumatic actuators are lubricated with lubricating grease on their bearings and guide rings before leaving the factory. Under normal operating conditions, lubrication must be carried out through an air oil mist device. All seals (including piston seals) can be made of nitrile rubber (standard type -20 ℃~+80 ℃), silicone rubber (low temperature type -40 ℃~+80 ℃), and fluororubber (high temperature type -20 ℃~+150 ℃).

Working principle of AT pneumatic actuator：
| When compressed air enters the middle chamber between the two pistons through hole A, the two pistons separate due to pressure. The air in the chambers at both ends of the cylinder is discharged through hole B, and at the same time, the central axis rotates counterclockwise by 90 °, and the corresponding valve also rotates counterclockwise by 90 ° to open | When compressed air enters the outer chambers of the two pistons from hole B, the pressure causes the two pistons to close towards the center. The air in the cylinder chamber is discharged through hole A, and at the same time, the central axis rotates 90 ° clockwise, and the corresponding valve also rotates 90 ° clockwise to close. |
