Pneumatic hard seal ball valve

Pneumatic hard seal ball valve

Brief description: Surface hardening treatment of the valve seat of pneumatic 

hard-sealing ball valve. The ball is spray-coated/spray-welded with carbide, 

and the sealing seat is spring-loaded. The scraper structure has excellent sealing 

performance within a wide range of temperature and pressure changes, ensuring 

stable operation under high temperature and high pressure conditions. This series of 

valves is mainly suitable for severe working conditions. It can meet severe working 

conditions such as high temperature, high pressure, wear resistance, strong corrosion and granular media.
