Low operating torque function

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

Rust-proof function

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

Anti-external leakage function

The upper seal features a 3-0-ring design to ensure no dripping during the dynamic movement ofthe valve stem; the middle flange adopts a self-sealing design, with the gasket utilizing the O-ringprinciple. The greater the pressure in the valve cavity, the tighter the rubber is compressed,resulting in more reliable sealing.

Anti-internal leakage functio

The gate plate is manufactured using advanced dualmode glue injection molding and high.temperature vulcanization processes. The rubber surface of the gate plate has no exposedpositioning points, achieving 100% full coverage. The rubber is evenly distributed with stabledimensions, ensuring excellent sealing performance.
