Fixed ball valve is a new generation of high performance ball valve. It is suitable for long-distance pipelines and general industrial pipelines. Its strength, safety and harsh environment are specially designed for various corrosive and non-corrosive media. The fixed ball valve has small torque, small deformation of the valve seat, stable sealing performance and long service life, and is suitable for high pressure and large diameter applications.
1. Double blocking and discharging function: It adopts a spring preloading floating valve seat. When the valve is in the fully open or fully closed state, the valve seat on the upstream and downstream sides blocks the fluid, and the retentate in the valve body is discharged through the discharge valve.
2. Automatic pressure relief function: When the valve body cavity stays in the medium temperature and causes abnormal pressure rise, it does not need to pass the safety valve. The valve seat function can automatically release pressure, which ensures the safety of the valve when conveying liquid medium.
3. Fire safety structure: the valve has fire safety function. Its design and manufacture are in accordance with API6D specifications.
