6. Rotation angle: double action =90 degrees, single acting =90 degrees, from both ends adjustable angle + 5 degrees.
7. Working environment temperature: -20, ~80 degrees.
8. Air source: filter, dry or refueling lubrication of clean air, minimum pressure 0.1Mpa, maximum pressure 1Mpa.
9. Basic design: pneumatic double cylinder, double piston shifting fork drive mechanism. Model AW= double acting; model AWS= single acting type (spring reset).
10. The AW series pneumatic devices are suitable for valves with 1/4 turning (90 rpm). Such as ball valve, butterfly valve, plug valve and so on. The design and manufacture of this product adopt JIS standard, and adopt the international standard ISO5211 with the valve connection department.

AW pneumatic actuator series function:
Double acting pneumatic actuator: two position control of valve opening and closing.
Spring reset: when the circuit is broken or broken, the valve opens or closes automatically.
Single electronically controlled solenoid valve: power supply valve open or closed, when the power off, the valve closed or open (can provide explosion-proof).
Double electronically controlled solenoid valve: one coil to power, the valve open, and the other coil to power, the valve closed, there is memory function (can provide explosion-proof type).
Limit switch back detector: signal that transmits the switch position of the valve remotely (can provide explosion proof type).
Electrical positioner: according to the current signal (standard 4-20mA) size of the valve medium flow adjustment control (can provide explosion-proof type).
Electrical converter: converts the current signal to an air pressure signal, which is used in conjunction with the pneumatic positioner (to provide an explosion proof type).
Air source treatment of triple parts: including air pressure reducing valve, filter, oil mist, the gas supply voltage, cleaning and moving parts lubrication.
Manual operating mechanism: automatic control can be operated manually under abnormal conditions.
AW pneumatic actuator series for use:
The use of AW pneumatic actuator, first determine the valve torque, considering the pipeline medium; water vapor or non lubricating medium increases 25% security value; non lubricated dry gas medium increases 60% security value; powder medium non lubricated gas transmission increases 100% security value; for cleaning, lubrication friction free medium a 20% increase in security value, then according to the source of work pressure, find the double action or single acting type torque meter, can get accurate actuator model.
Pneumatic actuator and valve installation accuracy is correct, and directly affect the safe operation and service life of the actuator. The reasonable installation is that the center shaft of the actuator and the valve stem must be absolutely coaxial and properly connected and installed. Before the actuator and valve are assembled, the torque shall be measured and shall not exceed the required torque. After the assembly, the pneumatic actuator and the wide doors at the same time test, the valve rated pressure to seal pressure, actuator to supply pressure of 4~8bar or according to user needs to switch the intake air pressure, the two inlet pneumatic actuator, pneumatic open and close observation of the situation of the valve, should not stop, the crawling phenomenon, should switch flexible smooth rotation, to repeat trials.
