Gate valve, also known as gate valve or gate valve, is the most widely used valve. It controls the opening and closing of the valve through the rising and falling of the gate. The gate is perpendicular to the fluid direction, and the channel size can be changed by changing the relative position between the gate and the valve seat.

1. The fluid resistance is small, and the sealing surface is less affected by medium brush and erosion.

2. It is easier to open and close.

3. The flow direction of the medium is not restricted, the flow is not disturbed and the pressure is not reduced.

4. Simple shape, short structure length, good manufacturing process and wide application range.
