Product Features

1. Valve seat adopts the structure of O-ring seals and pre-tightening float valve seat, the soft sealing inlays fluoroplastic, it provides the function of double sealing: fluoroplastic to metal and metal to metal. And at the same time, the fluoroplastic can remove the dirt of the gate disk.

2. Of the metal to metal sealing, there is a grease injection structure outside the valve, grease injects the sealing part through the seat, in this way achieves the aim of zero leakage.

3. Through conduit gate valve always coincide with the sealing surface,whether the disc is full open-or full closed; sealing surface to be protected from scouring by media directly, thereby extending the service life. In fulltime, smooth channel for the direct and flow resistance coefficient is extremely small, no pressure loss, leading to Pig.
