Pneumatic stainless steel plug valve introduction
Pneumatic stainless steel plug valve is componsed of sleeved plug valve or other structure plug valve and pneumatic actuator with double acting or sigle acting, Pneumatic stainless steel plug valve is a quick switch through valve, due to the movement between the rotary sealing surface with wiping effect, and in full open can completely prevent contact with the flow of media, Pneumatic stainless steel plug valve can usually also be used with suspension of the medium.Another important feature is that it is easy to adapt to a multi-channel structure, Pneumatic stainless steel plug valve can have two, three, or even four different flow channels.This simplifies the design of the piping system and reduces the number of valves and connections required in the equipment.

Pneumatic stainless steel plug valve advantages
1.Pneumatic stainless steel plug valve for frequent operation, open and close quickly, light.
2.Pneumatic stainless steel plug valve fluid resistance is small.
3.Pneumatic stainless steel plug valve is simple structure, relatively small volume, light weight, easy to maintain.
4.Good sealing performance.
5.Not limited by the direction of installation, the flow of the media can be arbitrary.
6. No vibration and little noise.
 
 Pneumatic stainless steel plug valve structure feature
1. The inlet and outlet channel of the Pneumatic stainless steel plug valve body is designed for the double-channel groove sealing ring structure, plug  in the process of rotation, the sealing pressure between the sealing pair changes gradually, until Pneumatic stainless steel plug valve reaches the fully open or fully closed position, produce enough specific pressure of the sealing pair to reach zero leakage.
2. The double-channel groove sealing ring of plug valve can not only stabilize PTFE bushing in the plug valve body without displacement, but also absorb the trace deformation of bushing caused by the change of temperature difference. At the same time, a powerful wiping effect can be generated between bushing and cock, and the service life of sealing surface can be improved.
3. The upper part of the plug shaft of Pneumatic stainless steel plug valve adopts a PTFE diaphragm, O-ring and adjusting gasket, which can adjust the specific pressure of sealing between the sealing surface, make the plug rotate flexibly, and ensure the sealing of the inlet and outlet ends and the connecting end of the middle flange.
4. The whole sealing process of the plug valve can be approximately considered to be independent of the pressure in the pipeline.
5. Pneumatic stainless steel plug valve PTFE liner, according to the use of temperature and working medium with different materials filling, good lubrication, long life.
