For secco nickel gate valve open-close part is ram, ram movement direction perpendicular to the direction of flow and the valve can only be fully open and close, not to adjust and throttling. Gate valve gate movement direction perpendicular to the direction of flow and the valve can only be fully open and close, not to adjust and throttling. Sealing face has two gate, two of the most commonly used mode gate valve sealing surface form a wedge, the wedge Angle vary with the valve parameters. Gate drive way classification: manual gate valves, pneumatic gate, electric gate valves.

For secco nickel material USES: British families is material has excellent corrosion resistance and high temperature performance, nickel-chromium alloy under the condition of high temperature has good oxidation resistance, carbide and chlorine gas medium. High nickel composition for reducing medium resistance and some organic and inorganic matter, the British families, he has very good avoid chloride stress corrosion crack. The British families, he has very good resistance to sulfide and a variety of oxide, chromium content in the British families, he make the soda ash excellent corrosion resistance in oxidizing.
