Feature of Soft Sealing Gate Valve1. Flat bottom, less dust accumulated, flow smoothly, switch easily.
2. Surface is coated with EPDM, no water or rust corrosion. Connected well with the board, not easy to drop off, and with good flexibility memory. Reliable sealing, anti-wear and no leakage.
3. Internal and external of Valve use nontoxic coating resin, enhance decay resistance capability, eliminate the second polluton to water.
4. The seal design uses three O-rings, which can make replacement and maintenance during water supplying.
Our Advantages:1. High quality material, more resistant to moisture and open-air environment.
2. Hand wheel surface thermal spaying epoxy resin powder coating, good looking and easy for cleaning, corrosion-resistant, perfect combination with valve life.
3. Copper Parts use HPb59-1 bar by forming multi-channel hot forging process, not annealed after forging, dense and weather resistance, no cracking, no internal stress.
4. Seals of EPDM rubber, water aging performace, life int he water longer than the NBR, guaranteed for 50 years.
5. Rubber vulcanization using advanced technology to ensure that iron is not exposed, don't contact water, no rust.
6. All valve flow cavity use heat pure epoxy powder coating, with small flow resistance. Pass 1500KV spark test, no rust, effectively prevent the second pollution from cast to water.
