► Design & Construction Of AT Series Double Acting Pneumatic Actuator


1. Full conformance to the latest specification: ISO5211DIN3337VD/VDE3845and NAMUR.
2. The extruding high-intensity aluminum body possesses a honed internal surface coated with hone anode oxygenation for long life, low coefficient of friction and swift performance.
3. Excellent, compact and modernized construction along with multi-specifications make the selection both economic and beneficial.
4. 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.
5. The same outline actuator has the functional modes of double acting and spring return, and the spring return has the normal-open and normal-close styles.
6. Multi-function position indicator with NUMER is convenient for mounting accessories.
7. Pre-compressed load spring is convenient for safe mounting and teardown procedures.
8. Die-casting aluminum pistons and end caps have high intensity and lightweight.
9. Different O-rings materials are available for high and low temperature.
10. According to different demands we can offer Multi-travel rotations (e.g. 120°135°180°) and three position actuators.
11. Solenoid valves are easily mounted without any connecting plank.



Pneumatic actuator attachment functions and uses of


1, double-acting actuators: valve opening and closing of two control.

2, single-acting actuator (spring return): In the circuit, gas cut off or fails, automatically close the valve.

3, single solenoid valve: open or close the supply valve, the valve closed or open, when power failure (explosion proof available).

4, double solenoid valve: a valve open when the coil is energized, the other coil is energized, the valve closes, with memory function (available in explosion-proof).

5, limit switch back to the hearing: long-distance transmission valve open or closed position signals (explosion proof available).

6, electrical locator: According to the current signal (4 ~ 20MA) the size of the media flow control valve control (available in explosion-proof).

7, pneumatic converter: the current signals into pressure signals, and supporting the use of pneumatic positioner (providing explosion proof).

8, pneumatic positioner: According to the current signal (Standard 0.02 ~ 0.1MPA) the size of the media flow control valve control.

9, Air Treatment FRL: including air relief valve, filter, lubricator. Of the gas source stable, clean and lubricate moving parts.
