Structural features of Structural features
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. It is tight and reliable. The sealing surface material of the ball valve is widely used in plastics and has good sealing performance. It has also been widely used in vacuum systems.
4. Convenient operation, rapid opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. A wide range of applications, from a small diameter to a few millimeters, as large as a few meters, and can be applied from high vacuum to high pressure
1. If the customer has special requirements for the product, the following instructions must be provided in the order contract:
