A gate valve is an opening and closing component, a gate plate

The movement direction of the gate valve is perpendicular to the direction of the fluid, and the gate valve can only be fully open and fully closed, and cannot be adjusted or throttled. Gate valves are sealed by the contact between the valve seat and the gate plate. Usually, the sealing surface is welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. There are rigid and elastic gate valves, and gate valves are divided into rigid gate valves and elastic gate valves according to the different types of gates.
