Products Design Features
Gate valve is one of the most commonly used cut-off valves, it*s mainly used to connect and disconnect media in pipe. The range of suitable pressure, temperature and caliber is very wide. It is widely used in water supply and drainage, gas, electric power, petroleum, chemical industry, metallurgy and other industrial pipeline which media is steam, water, oil to cut off or adjust the flow of media.

Product structure characteristics
A check valve is an “automatic” valve that is opened for downstream flow and closed for counter-flow.Open the valve by the pressure of the medium in the system, and close the valve when the medium flows backwards.The operation varies with the type of check valve mechanism.The most common types of check valves are swing, lift (plug and ball), butterfly, check, and tilting disc.Products are widely used in petroleum, chemical, pharmaceutical, chemica...
