Low operating torque function

The valve torque can be easily closed at 80% of the nominal diameter, achieving zero leakageunder nominal pressure.

Anti-rust function

The valve cover and gland adopt countersunk wax sealing design, and the bolts are not exposedwhich completely solves the problem of bolt rust

Anti-leakage function

The upper seal adopts 3-way molded filler and O-ring double sealing design to ensure that thevalve stem is dynamic and leak-proof; the middle flange is self-sealing, and the sealing gaskeadopts the principle of O-ring. The areater the pressure in the middle cavity, the more reliable the seal

Anti-internalleakage function

The gate adopts advanced dual-mold injection molding and high-temperature vulcanizationprocess. There is no exposed positioning point on the gate rubber surface, 100% full coverage.uniform rubber, stable size, and good sealing performance.
