Valve advantages

1 fluid resistance small, the drag coefficient with the same length of pipe equal.
2 has the advantages of simple structure, small volume, light weight.
3 closely reliable, current Instrument needle valve sealing surface material widely used plastic, good sealing performance, in the vacuum system has also been widely used.
4, the operation is convenient, quick open and close, from fully open to fully closed as long as the rotation of 90 DEG, facilitate remote control.
5 ball Instrumentation ball valve has the advantages of simple structure, convenient maintenance, seals are generally activities, the removal of the replacement is more convenient.
6 in the fully open or fully closed, the ball and seat sealing surface and the dielectric isolation, through the media will not cause erosion of the valve sealing surface.
The 7 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.
