Floor Type Hydrostatic Pressure Relief Valve

Hydrostatic pressure relief valves are used to equalize pressure between groundwater and within tanks and digesters to prevent tank floating.

Floor type hydrostatic pressure relief valve.

Hydrostatic pressure relief valves ensure that concrete tanks don t float from the excess groundwater beneath them. Floor type pressure relief valves performance under pressure located on the bottom of a tank floor type pressure relief valves open up when excess groundwater is present to prevent floating which can cause cracking and other serious issues. Floor type model prf 15 and wall mounted model prb 14 hydrostatic pressure relief valves. The assembly shall consist of three parts.

The increase over hydrostatic pressure that occurs from rising water tables triggers the opening of the pressure relief valve allowing water to enter the tank. Trumbull floor type tank pressure relief valves are cast in the bottom of tanks in treatment plants to keep empty tanks from fl oating from an excess of groundwater beneath them. The waterman model prf 15 hydrostatic pressure relief valve is the newest in a series of effective floor relief valves. When this condition occurs the hydrostatic pressure will open the cover of the valve allowing water to enter thereby equalizing pressure inside and outside.

They shall be designed so that neither the cover. Cover body and grate. Floor type hydrostatic pressure relief valve shall be designed for installing in the bottom of concrete tanks. When this condition occurs the hydrostatic pressure will open the cover of the valve allowing water to enter thereby equalizing pressure inside and outside the tank.

All three parts shall be of cast iron conforming to astm specifications a 126 class b. The groundwater pressure increase triggers the valve to open.
