Pneumatic actuator
The extruded high-quality aluminum alloy cylinder
With Hard Anode Oxidation treatment
Easy installation
Summary:
The pneumatic actuator widely used kinds of Rotary travel type control valve. The inner surface of the cylinder is treated by Hard Anode Oxidation which have many advantages such as high strength, low weight, quick reaction, easy to clean, long-life and high confriction. The piston adopts the aluminium die-casting process, the surface is also done by Hard Anode Oxidation treatment with high intensity, strong tenacity and wearability. And this type actuator is favored by extensive users both at home and abroad. The extruding high intensity aluminum body possess a honed internal surface coated with hone anode oxygenation for long life, low coefficient of friction and swift performance.

Advantage:
Excellent, compact and modernized construction along with multi-specifications make the selection both economic and beneficial.
All acting surfaces adopt high quality bearings, resulting in low friction, high cycle life and no noise.
The two independent external travel stop adjustment bolts can easily and precisely adjust ± 5° At both open and close directions.
Same outline actuator have the functional modes of double acting and spring, and the spring return has the normal-open and normal-close styles.
Multi-function position indicator with NUMER is convenient for mounting accessories.
Pre-compressed load spring is convenient for safe mounting and teardown 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.
According to different demands we can offer Multi-travel rotations (e. G. 120° 135° 180° ) and three position actuators.
Solenoid valves are easily mounted without any connecting plank.
