Floor Type Hydrostatic Pressure Relief Valve

When this condition occurs the hydrostatic pressure will open the cover of the valve allowing water to enter thereby equalizing pressure inside and outside. Trumbull floor type tank pressure relief valves are cast in the bottom of tanks of treatment plants to keep empty tanks from floating from an excess of groundwater beneath them. Hydrostatic pressure relief valves are used to equalize pressure between groundwater and within tanks and digesters to prevent tank floating.
