Anderson Greenwood 4000 Series pressure and vacuum relief valves

Anderson Greenwood 4000 Series high-capacity, full-lift pressure and vacuum relief valves meet the requirements of the seventh edition of API 2000 for vapor venting requirements of bulk storage tanks. The valves fully open at 10% overpressure, so they can be set closer to the maximum allowable working pressure or vacuum, allowing tanks to be filled and emptied more quickly and operated at higher pressures for increased productivity and reduced evaporation.
