Description:Features: 1) Flat bottom seat: Traditional gate valves are often deposited with external matters like stone, wood, cement, iron filing and impurity in the scoop channel of the valve bottom after being washed by water, so they can not close intensively and leakage exists there. Flexible seat sealing gate valves use the same flat bottom design as pipes, so it is not easy for impurity to deposit there and the flow is more fluent 2) The whole body is glue wrapped: The valve uses high quality rubber to wrap the internal and external parts. The first-class European rubber sulphurization technology makes the valve have precise geometrical dimensions after being sulphurized, and rubber is tightly cohered to the ductile cast iron valve, it does not drop easily and has good flexibility memory 3) Precisely cast valve body: The valve body is precisely cast, accurate geometric dimensions make the internal of valve to ensure sealing ability without any precise fabrication 4) Corrosion-proof: The body is painted with powder epoxy resin, and it can avoid corrosion and rust, and can be used in foul water system 5) 3 O-rings sealing: Because the stem utilizes 3 O-rings sealing design, the shut-off friction resistance is reduced, leakage can be greatly reduced and we can replace seal rings without stopping supplying water 6) Helpful to use unboiled water: Because the internal of valve is painted with innoxious epoxy resin, the internal and external surfaces are both covered with rubber so that it is impossible for rust water or corrosion phenomena to take place and the water can be drunk without being boiled
