Cast Iron Water Seal Gate Valves

Following are the Main Features of Cast Iron Water Seal Gate Valves :-
1. Adopt rubber and water dual seal type, rubber seal can play a part of basic seal function and keep water staying in the valve body to ensure zero leakage. On environmental and safety aspect it is a new product which replaced the flap valve. In cold weather, can add antifreezing or use nitrogen and other ignition-proof gas to instead water.
2. Adopt dual-gate dual-direction elastic sealings, fluororubber material of main seal ring which is even more durable.
3. Stainless steel internal connection, ensure long service life.
4. Equipped with drainage ball valve, it can not only clean the inside cavity but also clean the impurities that remaining in the valve body during the drainage process.
5. Adopt high-performance fillers of small frictional resistance, self-lubricating, coal gas and all kinds of corrosive gas resistance, reliable sealing.
