Name: manufacturer of pneumatic valve with bevel gear for pneumatic actuator
Technical parameters and transmission principle of pneumatic valve actuator
Equipment for remote centralized or separate control of industrial automation pipeline
The pneumatic valve actuator is driven by compressed air and is the driving device of pneumatic ball valve, pneumatic butterfly valve, pneumatic gate valve, pneumatic stop valve, pneumatic diaphragm valve, pneumatic control valve and other pneumatic series travel valves. It is an ideal device to realize long distance centralized or independent control of industrial automation pipeline.

Transmission principle
When the compressed air enters the pneumatic actuator, the gas will move the double pistons directly to both ends, and the rack on the piston will rotate the gear on the rotating shaft 90 ° counterclockwise to open the valve. At this time, the gas at both ends of the pneumatic actuator pushes the double pistons in a straight line towards the middle along with the gas at nozzle B. The teeth on the piston drive the teeth on the rotating shaft to rotate 90 ℃ clockwise, and the valve will close soon. At this time, the gas in the middle of the pneumatic actuator is discharged with nozzle A. The above is the standard transmission principle. According to the user's requirements, the pneumatic actuator can be installed with the transmission principle opposite to the standard type, that is, the rotating shaft rotates clockwise to open the valve and counterclockwise to close the valve.
Nozzle A of the pneumatic actuator is the air inlet, single acting (spring return), nozzle A of exhaust pipe B (muffler installation) is the opening valve, and the valve is closed with spring force when the air is cut off.
