Product advantages:

1. Full welded structure valve body, no external leakage. Compact valve structure , easy for construction and installation.
2. Valve seat and O-ring are made of impored raw marterials. Excellent self-lubrication, low friction coefficient, high structure density and good anti-aging performance.
3. Anti blowout structure and the center shaft and the center shaft sealing system are replaceable.
4. Single side double seal valve seat (double side quadruple seal) greatly increases the service life of the valve.
5. Each valve will be inspected for shell and seal pressure before leaving factory.
