In order to meet these requirements as fully as possible the vacuum valves are divided according to size type of flange and drive and according to the pressure range used.
In the simplest of terms vacuum gate valves are devices that regulate the flow of gases fluids or materials through a structure or aperture by opening closing or obstructing a port or passageway.
