Installation and maintenance
1, the pneumatic actuator can be directly connected with the valve, brackets and fittings can also be connected with the valve installation. Fasteners must not loose connection.
2, to ensure that the actuator output shaft coaxial with the valve stem is installed, and turn the flexible non-crawling phenomenon.
3, connecting pipes, fittings, accessories, etc. should be clean.
4, solenoid valve scheduled port is always down, when the level up or when the pipe should be connected so that the exhaust downward.
5, testing should be determined before the channel clear air, pressure, voltage, signals meet the requirements.
6, compressed air should be filtered, dried, dew point -15 ℃ to dehumidify the following.
7, solenoid valve should open when debugging to the automatic position.
8, pneumatic operation, the device should be disconnected manually, manually operated pneumatic devices should be disconnected.
9, the actuator is installed on a variety of accessories, should be separately described with reference to use for debugging,
10, under normal operating conditions once a month, once a year overhaul.

► 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.
