PVC compact ball valve DN100 specifications for double bevel design, under the action of the spring, the valve can self-compensation sealing, to ensure that it has good sealing performance in the middle and low pressure, the service life is also relatively long. Above DN100, fixed ball structure is used to ensure the performance. Only in the stem and cover contact place packing, reduce the valve closing, closing torque, than the ordinary valve 20%. The sphere is loaded from the top to facilitate field repair and replacement of parts.

PVC compact ball valve is a new type of valve 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 a pipe section of the same length.

2. Simple structure, small size, light weight.

3. Tight and reliable, the sealing surface material of ball valve is widely used in plastic, good sealing, and has been widely used in vacuum system.

4. Easy to operate, open and close quickly, from fully open to fully closed as long as the rotation of 90°, convenient for remote control.

5. Convenient maintenance, ball valve structure is simple, sealing ring is generally active, disassembly and replacement are more convenient.

6. When fully open or fully closed, the sealing surface of the ball and seat is isolated from the medium. When the medium passes, it will not cause the erosion of the sealing surface of the valve.

7. A wide range of applications, from small diameter to a few millimeters, to a few meters, from high vacuum to high pressure applications.
