Product Overview

The Model 5100 end-of-pipe Pressure Vacuum Relief Valve maintains a seal. When system pressure or vacuum exceeds the valve's setting, the spool lifts and the seal between the seat and spool is broken, releasing the pressure or vacuum buildup, and once the release is complete, the valve maintains the seal again.
Installation position: connected to the tank through the flange, the valve is opened and discharged directly to the atmosphere
