Gate Valve are mainly used in pipelines to cut off quickly, 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. It has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the 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
Universal 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, just 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 range from a few millimeters to several meters, and can be used from high vacuum to high pressure.
8. Because the Gate Valve power source uses gas, the pressure is generally 0.2-0.8MPa, which is relatively safe. If the Gate Valve leaks, the gas can be discharged directly compared to hydraulic and electric valves, which does not pollute the environment and has higher safety.
9. Compared with manual and turbine rotating Universal Valve, Gate Valve can be configured with large diameters. Gate Valve have been widely used in various departments such as petroleum, chemical industry, power generation, papermaking, atomic energy, aviation, rockets, and people's daily lives.Universal Valve
