pneumatic rotary actuator
AT series DA(double acting) and SR(Spring Return) Pneumatic Actuators are mainly for Pneumatic Butterfly Valve and Pneumatic Ball Valve.
AT series pneumatic actuators statement 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 actuator 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.
Pneumatic 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.
