Introduction To Gate Valve

The gate valve is a gate that opens and closes. The movement direction of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate valve is sealed through the contact between the valve seat and the gate plate. Usually the sealing surface is surfacing with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. Gates include rigid gates and elastic gates. According to the different gates, gate valves are divided into rigid gate valves and elastic gate valves.
