Gate Valve

The opening and closing part of the gate valve is a gate, and 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, and the sealing surface is usually welded with metal materials to increase wear resistance, such as 1Cr13, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate. According to the difference of the gate, the gate valve is divided into a rigid gate valve and an elastic gate valve.

Gate valve is a widely used valve. Generally, cut-off devices with a diameter of DN≥50 mm are selected for use. Sometimes gate valves are also used for cut-off devices with small diameters. Gate valves have the following advantages:

①The fluid resistance is small.

②The external force required for opening and closing is small.

③The flow direction of the medium is not restricted.

④When fully open, the erosion of the sealing surface by the working medium is smaller than that of the stop valve.

⑤The body shape is relatively simple, and the casting process is better
