Gate valve is an opening and closing shutter. The direction of movement of the gate is perpendicular to the direction of the flow. 

The gate valve can only be fully opened and fully closed and cannot be adjusted or throttled. The gate valve is sealed through contact between the valve seat and the gate plate. Usually, the sealing surface will be surfacing with a metal material to increase the wear resistance, such as surfacing 1Cr13, STL6, stainless steel, and the like. The gate plate has solid gate plate and flexible gate plate.
