Product Features

Simple structure, small external size, short structure length, small volume, light weight, suitable for large diameter valves.
When fully open, the effective flow area of the seat channel is large and the fluid resistance is small.
Convenient opening and closing, fast, good adjustment performance.
The opening and closing moment is small, because the disc on both sides of the rotating shaft acts almost equally on the medium, and the direction of the torque is opposite, so the opening and closing needs less effort.
Sealing surface materials are generally rubber and plastic, so the low-pressure sealing performance is good.
Precision casting valve body. Qualified WCB material. Fine appearance, no trachoma.
The PTFE valve seat is integrally die-cast and then machined. To ensure density and tightness.
Double sealing rings design to avid the leakage from shaft.
