Pneumatic Actuator
Pneumatic actuators are composed of a simple piston inside a hollow cylinder. The position of a pneumatic actuator is controlled by regulating the air into the valves, which moves the piston within the cylinder housing against the spring force. When there's no air pressure, the spring force moves the piston back to its original home position.
Electric actuators convert the rotational force of an electric motor into a linear force with a specific mechanism, such as a ball screw. By rotating the actuator's screw with the motor, the ball screw nut will move along the screw forward or backward. The position of an electric actuator is controlled by regulating voltage and current.
1.Output torque:
Double acting : Up to 13024Nm
Spring return : Up to 9523Nm
2.Working pressure:
Double acting : 2.5bar~8bar
Spring return : 2.5bar~8bar
3.Working temperature:
-20℃ ~ +80℃ : In standard construction
-35℃ ~ +80℃ : With Nitrile butadiene rubber (NBR) O-rings ( low temperature execution)
-15℃ ~ +150℃ : With fluororubber (FKM) O-rings ( high temperature execution)
Pneumatic actuator control valvesstatement of usage and selection
The extruding high intensity aluminum body possesses a honed internal surface coated with hard anode oxygenation for long life. Low coefficient of friction and swift performance.
Excellent compact and modernized construction along with multi specifications makes the selection both economic and beneficial.
All acting surface adopt high quality bearing resulting in low friction, high cycle life, and no noise
The two independent external stroke adjustment bolts can easily and precisely adjust ±5°at both open and close directions.
Same outline actuators have the functional modes of double acting and single acting (Spring -Return). The Spring-Return has the normally-open and normally-close styles.
Multi function indicator with NAMUR is convenient for mounting accessories.
Pre-compressed load spring is convenient for safe mounting and tear down procedures.
Die-casting aluminum pistons and end caps have high intensity and light weight.
Different O-rings materials are available for high and low temperature.
Product Application
AT series Pneumatic Actuator is made of dual pistons driven by racks and pinions. There are two models. One is Dual Acting model, and the other is Spring Return model, which can suit various flammable, corrosive, dusty, strong magnetic field, radiation, vibration corrosive environment indoor or outdoor.
Auto-control in the field of electric power, petrochemical, metallurgy, petroleum, gas, town, construction, drainage, chemical industry, oil refining, mining, power plant, metallurgy, architecture, medicine, food, gas, scientific research, etc.
