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
The insulation gate valve is used for some heat preservation media. The heat preservation design can prevent the solidification or crystallization of heat transfer oil, steam and other media at room temperature.

It is stable and reliable when used in pipelines, so flange gate valves are often used in high-pressure pipelines. The Gate Valve With Electric Actuator is a remote automatic control gate valve, which is driven by the power source to drive the valve stem to move up and down, thereby controlling the opening and closing of the gate valve.
Read MoreSend InquiryThe brass thread gate valve is widely used and belongs to the forced sealing valve. Its closing principle is to rely on the pressure of the valve stem to make the sealing surface of the disc and the sealing surface of the valve seat closely fit to prevent the medium from flowing.
Read MoreSend InquiryThe industrial gate valve is mainly used to cut off and connect the medium in the pipeline. The industrial gate valve is a kind of valve used in the pipeline. There are only two forms of industrial gate valve in the pipeline, which are fully open or fully closed, and can not be semi open, and can not be used to control the medium flow.

Read MoreSend InquiryStainless steel flange gate valve is an on / off control valve, used to transfer or cut off the medium. The opening and closing part of the stainless steel flange gate valve is the gate. The movement direction of the gate is perpendicular to the fluid direction. When the valve plate falls down, the valve closes to prevent the medium from flowing. When the valve plate rises, the valve opens and the medium can pass through the valve. Stainless steel flanged gate valves can only be fully opened and fully closed.
