Product Description

Product Description
The eccentric hemispherical valve is a relatively new type of ball valve. It has some advantages unique to its own structure, such as frictionless switch, not easy to wear, and small opening and closing torque. This can reduce the size of the actuator. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is widely used in working conditions that require strict cut-off such as petroleum, chemical industry, urban water supply and drainage.

advantage
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. At present, the sealing surface material of the ball valve is widely used in plastics with good sealing performance, and it has also been widely used in the vacuum system.
4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. The maintenance is convenient, the structure of the ball valve is simple, the sealing ring is generally movable, and it is convenient 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. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
