Insulation ball valve and flange gate valve is the same type of valve, the difference in its closure is a sphere, the ball around the body center line rotation to achieve the opening and closing of a valve. Ball valve in the pipeline is mainly used for cutting, distribution and change the direction of the flow of media. Two piece ball valve, three piece ball valve, is widely used in recent years, a new type of valve, the valve installed in general level.

1 fluid resistance is small, and its resistance coefficient is equal to the length of the pipe section.

2 simple structure, small size, light weight.

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

4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.

5 easy maintenance, ball valve structure is simple, seals are generally active, disassembly and replacement are more convenient.

6 in the fully open or fully closed, the ball and valve seat sealing surface and the dielectric isolation, the medium through, will not cause erosion of the valve sealing surface.

7 a wide range of applications, from small to a few millimeters in diameter, up to a few meters from the high vacuum high pressure can be applied. When the ball is rotated 90 degrees, the surface of the inlet and outlet should be completely spherical, thus cutting off the flow.

Thermal insulation ball valve is a new type of ball valve, it has its own unique advantages of the structure, such as the switch without friction, seal is not easy to wear, opening and closing torque is small. This reduces the size of the actuator. Equipped with multi turn electric actuator, which can adjust the medium and cut off tightly. It is widely used in [wiki] oil [/wiki], [wiki] chemical [/wiki], urban water supply and drainage and so on.
