Gate Valve and plug valves are valves of the same type, except that the closing part is a sphere, which rotates around the center line of the valve body to open and close.
Gate Valve are mainly used in pipelines to cut off, distribute and change the flow direction of the medium. Gate Valve are a new type of valve that has been widely used in recent years. They have the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
2. Simple structure, small size and light weight.
3. Tight and reliable. At present, the sealing surface material of Gate Valve widely uses plastics with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, open and close quickly, and only need to rotate 90° from full open to full closed, which is convenient for long-distance control.
5. Easy maintenance, the Gate Valve has a simple structure, and the sealing ring is generally movable, which is convenient for disassembly and replacement.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes, it will not cause erosion of the valve sealing surface.
7. Wide range of applications, diameters from a few millimeters to several meters, and can be used from high vacuum to high pressure.
Gate Valve have been widely used in various sectors such as petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets, and people's daily lives.
