Nupro® Shut-Off Gas Valves

For gas shut-off applications, we offer two series of Nupro® 316 stainless steel valves, the H-series and the B-series. The compact H-series valves cover most gas applications in vacuum processing. The B-series valves feature demountable bonnets which allow easy maintenance or cleaning of the valve seat.
