When fully open or fully closed, the sealing surface and the dielectric isolation ball and seat, through the media, will not cause erosion of the valve sealing surface. 7. Wide range of applications, from small diameter to a few millimeters to a few meters from high vacuum to high pressure can be applied. This type valve in the pipe should generally be installed horizontally.
