Gate valves are widely used in various industrial applications, including chemical, petroleum, natural gas, electricity, pharmaceuticals, food processing, etc., to control the flow of fluids (liquids, gases or steam), usually used to cut off and open and close the flow of fluids. The sealing performance of the gate valve is one of its key characteristics, and it is usually sealed by the contact between the valve seat and the gate.
