Three-piece ball valve installation and maintenance should note the following:

    1. To leave the position of the handle.

    2. Can not be used as a throttling.

    3 Ball valves with transmission mechanism should be installed upright.

Eccentric ball valve works by rotating the valve to make the valve, butterfly valve, filter, ball valve, trap, hydraulic control valve open or closed. Ball valve switch light, small size, can be made into a large caliber, sealed and reliable, simple structure, easy maintenance, sealing surface and the ball often closed state, not easily eroded by the media, in various industries have been widely used.

Insulated ball valves are mainly used in piping to cut, distribute and change the flow direction of the media. Ball valve is widely used in recent years, a new type of valve, it has the following advantages:

    1. Fluid resistance is small, the resistance coefficient and the same length of the pipe section equal.

    2. Simple structure, small size, light weight.

    3. Close and reliable, the current ball valve sealing material widely used plastic, good sealing, in the vacuum system has also been widely used.

    4. Easy to operate, open and close quickly, from full open to full clearance as long as 90 ° rotation, easy to control the distance.

    5. Easy maintenance, ball valve structure is simple, the seals are generally active, demolition and replacement are more convenient.

    6. When fully open or fully closed, the ball and valve seat sealing surface and the media isolation, the media through, will not cause the valve sealing surface erosion.

    7. Applicable to a wide range of diameter from small to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated by 90 degrees, the spherical surface should be present at the entrance and exit, thus breaking the flow.
