The pneumatic ball valve has small flow resistance, unrestricted flow direction, and quick opening and closing. Compared with other types of valves, it has good comprehensive performance advantages. It is also a key research topic for domestic and foreign valve manufacturers. If the sealing surface material of the pneumatic ball valve is made of non-metallic materials such as tetrafluoroethylene, nylon 1010, polyimide, etc., the specific pressure q 20 MPa and temperature t 180 ℃ that the sealing material bears have greatly limited the application field of the pneumatic ball valve. At present, the sealing surface of domestic metal sealed pneumatic ball valve adopts nitriding treatment, hard chromium plating or spray welding CoCrW hard alloy and other hardening processes, but still can not solve the defects of sealing surface scratch under high pressure and wear resistance decline of sealing surface under high temperature. The project adopts spraying and other processes, and different spraying methods are adopted according to the service conditions, which can meet the requirements of valve operating parameters to the maximum extent.

Pneumatic butterfly valve storm arouses central talent
Pneumatic butterfly valve enterprises have one or more central talents, which is also equal to establishing the safety of the foundation; With security, we can spare no effort to build up our competitiveness. Establishing competitiveness requires resources, and the provision of this resource is the value conversion from the central talent. So, how does our company deal with the compound vibration of pneumatic butterfly valve?
There are two methods of using pneumatic butterfly valve to deal with compound vibration:
1. Two pneumatic butterfly valve vertical devices are used;
2. Corrugated pneumatic butterfly valve 90 ° bending device.
