A2180 Air Relief Valve, 20 PSI

Dixon, A2180/20ADJ, A2180 Air Relief Valve Adjustable Pressure, 20 PSIApplicationsDesigned specifically for use on trailer tanks containing dry bulk products. If a system blockage were to occur, the valves are designed to vent to atmosphere once the valve pressure setting is achieved. The advantage of the adjustable air relief valve is that the factory preset pressure can be tuned by -3/+3 PSI to meet tank/application specific pressure requirements (adjustments should be performed by either the tank builder or tank maintenance facility).UseValves have a +1/-0 pressure tolerance (valve opens at set pressure plus 1 PSI) and are adjustable by -3/+3 PSI.Trailer/Tank MountedSpecificationsRelieving capacity: 500 to 950 SCFMFeaturesInstalled cup seal deters tamperingBayloy body eliminates thread gallingThe factory preset pressure can be tuned by -3/+3 PSI to meet tank/application specific pressure requirements (adjustments should be performed by either the tank builder or tank maintenance facility).ConstructionBayloy vent cowl with aluminum upperBronze poppetWhite food grade silicone diaphragmNoteRelieving capacity (SCFM) varies dependent upon model and pressure setting.
