Not easy to siltation caused by debris. The fluid unimpeded.
The overall rubber coating: Valve is coated rubber as a whole with high-quality rubber. Domestic first-class rubber vulcanization technology ensures valve after curing of precise geometry size and make the rubber adheres firmly to ductile iron valves . Not easy to fall off and good elastic memory.
Three "O" type seal ring: It can reduce the frictional resistance caused by opening and closing and significantly reduce water leakage as the stem is used with sealing design of three "O" type sealing ring .
