Overview and Application
The surface of the valve seat of the pneumatic hard-sealing ball valve is hardened. 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.
