Thermal insulation ball valve and flange gate valve is belong to the same type of valve, the difference between its closure is a ball, the ball around the body center line for the rotation to achieve the open, close a valve. Ball valve in the pipeline is mainly used to do the 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 general level of the installation of such valves.
Thermal insulation ball valve is a relatively new type of ball valve, it has its own unique structure of some of the advantages, 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, can realize the adjustment of the medium and tight cut off. Widely used in oil / chemical / metallurgy / pharmaceutical / city water supply and drainage, such as strict cut-off conditions.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, caliber. Specific please contact or online advisory contact.
1 fluid resistance is small, and its resistance coefficient is equal to that of the same length.
2 simple structure, small size, light weight.
3 close and reliable, the current 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 maintenance convenient, simple structure, the sealing ring is generally active, demolition 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 media through, will not cause the valve sealing surface erosion.
7 wide range of applications, from small to a few millimeters diameter, large to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, the inlet and outlet of the ball should be all of the spherical surface, thus cutting off the flow.
