The gate valve is an opening and closing gate. 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 by the contact between the valve seat and the gate plate.
Usually, the sealing surface will be surfacing with metal materials to increase wear resistance, such as surfacing 1Cr13, STL6, stainless steel, etc.
The gate has a rigid gate and an elastic gate. According to the different gates, the gate valve is divided into a rigid gate valve and an elastic gate valve.
