Low operating torque function

The valve can be easily closed with a torque of 80% of the nominal diameter, achieving zeroleakage under nominal pressure.

Anti-rust function

The bonnet and gland adopt a countersunk wax-sealing design, with no exposed bolts, completelysolving the problem of bolt rusting.

Anti-external leakage function

The upper seal is designed with three O-rings to ensure no water leakage during the dynamicmovement of the valve stem; the middle flange adopts a self-sealing design, and the gasket isbased on the O-ring principle. The greater the pressure in the valve chamber, the tighter the rubbelis squeezed, and the more reliable the sealing becomes.

Anti-internal leakage functio

The gate adopts anadvanced dual-mode glue-injection molding and high-temperaturevulcanization process. The rubber surface of the gate has no exposed positioning points, with100%full coverage,uniform rubber thickness, stable dimensions, and excellent sealingperformance.
