Introduction of soft sealing gate valve flange

A Traditional valve intracavity a cavity at the bottom, making it easy for debris deposition, and could not shut down close, resulting in leakage of the valve
formation at the bottom, it is not easy plot debris, fluid unimpeded, switching easily.
B Ram EPDM rubber-coated surface are selected materials used meet the health standards gB/T17219-1998, without any water or rust corrosion
phenomenon for Health drink And connecting with the ram Solid, not good memory loss and flexibility. Seal reliable, anti-wear, leakage rate of zero.
C Valve internal and external use nontoxic coating resins, resin meet sanitary conditions, and enhance decay resistance capacity, eliminating the secondary
pollution on the water quality.
D Stem nut embedded gate, so that it will not loosen or vulnerable to corrosion, long service life.
E. The seal design uses threeo'-rings can be kept water replacement, maintenance, maintenance.
