Structure Character/结构特点

- Flat bottom seat
   Resilient soft seat gate valve appy the same flat bottom design as pipse.It prevents the pipe from       debris deposition, and maintain pipeline unblocked. - The whole body is eubber lined.The valve uses       high quality rubber to line internal and external parts.The first- class rubber vulcanization    technology ensure the valve with precise dimension. The rubber is tightly lined on the parts.
- Corrosion resistance
  The body is coated with epoxy resion powder, anti-corrosion and anti-rust.
- 3 O-rings sealing
   3 O-rings sealing design at shaft, it reduce the frictional resistance when open and close, and    significantly reduce water leakage and we can replace the seal rings without closing water supply.
