Features
· Cylinder plus fork structure, have double-acting and single acting (spring return) two forms.
· Cylinder capacity is large, a larger torque can be output, suitable for Angular travel industry valve like medium and large diameter butterfly valves,ball valves.
· Section connected with valve using international standard ISO5211.
· According to user requirements, in pneumatic actuator could install Solenoid valves, positioners,Reply device,Filter regulator,Various limit switches and Manual operating mechanism ect.

Double-acting

Internal structure:

Double-acting actuator for the two-cylinder, large output.Air pressure: 0.3-0.7MPa,Used for large diameter valves. Its fork's output torque havesimilar characteristics with operating torque of large diameter valves.
Single acting (spring return)

Internal structure:

Single acting spring return,,One cylinder a spring, When faults occur can close or open the valve, safe and reliable.Output torque than the double-acting small.Air pressure: 0.4-0.6MPa.

The main technical parameters
1, the use of media: clean, dry and free of corrosive compressed air; air pressure: 0.3 ~ 0.7MPa
2,Operating ambient temperature: Standard: -20 ℃ ~ + 80 ℃ High temperature: 0 ℃ ~ + 180 ℃
3,the output torque: BAW double-acting pneumatic actuators are shown in Table 1; BAW single-acting (spring return) pneumatic actuator Table 2

Selection Help:
Before use pneumatic actuators,First consider the valve pressure, temperature, medium form,Then determine the valve torque: lubricating fluid to increase 20% safety factor ；Medium powder particles increase 65% safety factor of,Then choose double-acting or single-acting pneumatic actuator according to air pressure, and to determine the model.
