]Three way ball valve in the structure of the integrated structure, 4 seat sealing surface type, less flange connection, high reliability, design and implementation of a lightweight, long service life, large flow capacity, small resistance, three way ball valve has the following advantages:
1, fluid resistance small, the drag coefficient with the same length of pipe equal.
2, three way ball valve has the advantages of simple structure, small volume, 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, three way ball valve has the advantages of convenient operation, rapid opening and closing, from fully open to fully closed as long as the rotation of 90 DEG, facilitate remote control.
5, convenient maintenance, simple ball valve, seals are generally activities, the removal of the replacement is more convenient.
6, in the fully open or fully closed, the ball and seat three valve sealing surface and the dielectric isolation, through the media will not cause erosion of the valve sealing surface.
7, three ball valve is suitable for a wide range, from small diameter to a few millimeters, a few meters from the large, high vacuum high pressure can be applied.
