Pneumatic Actuator
What is a pneumatic actuator?
By definition, a pneumatic actuator is a device that converts energy typically in the form of compressed air into mechanical motion. Within the industry, pneumatic actuators are recognised by several different names including pneumatic cylinders, air cylinders, and air actuators; all of which are one and the same.
Consisting of a piston, cylinder, and valves or ports, a pneumatic actuator can convert energy into linear or rotary mechanical motions. This is dependent on whether the application is using a pneumatic rotary actuator or a linear actuator.
Linear actuators are well suited for fitting to angle seat control valves built for high temperature and steam applications, whereas the pneumatic rotary actuators are better suited for fitting to quarter-turn valves depending on the specification of the application.

Pneumatic Actuator Design Feature
- Through research development and design AT series pneumatic actuators incorporate the latest technology materials and innovative idea. The product proudly boasts the following features.
- Full conformance to the latest specifications: ISO5211,DIN3337 and VDINDE-3854,NAMUR.
-
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.
- Solenoid valves are easily mounted without any connecting plank.
