ACS Valves Run-Clean rotary airlock valves feature angled surfaces and rounded edges inside the housing to eliminate dead zones. Factory-applied internal surface coatings such as tungsten prevent surface wear imperfections where material can build up; glandless, sleeve-style shaft seals prevent contaminant migration into the housing. The valves are available in 304 or 316 stainless steel, in sizes from 6 to 18 in., with pressure differentials up to 20 psig and a temperature tolerance up to 750°F.
