Floor Type Hydrostatic Pressure Relief Valve

Floor type hydrostatic pressure relief valve shall be designed for installing in the bottom of concrete tanks. 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. Floor type model prf 15 and wall mounted model prb 14 hydrostatic pressure relief valves.

Floor type hydrostatic pressure relief valve.

The groundwater pressure increase triggers the valve to open. When this condition occurs the hydrostatic pressure will open the cover of the valve allowing water to enter thereby equalizing pressure inside and outside. Hydrostatic pressure relief valves are used to equalize pressure between groundwater and within tanks and digesters to prevent tank floating. 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.

Hydrostatic pressure relief valves ensure that concrete tanks don t float from the excess groundwater beneath them. The assembly shall consist of three parts. They shall be designed so that neither the cover. The waterman model prf 15 hydrostatic pressure relief valve is the newest in a series of effective floor relief valves.

Floating tanks can lead to serious cracks and other major issues. All three parts shall be of cast iron conforming to astm specifications a 126 class b. 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. 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.

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. Cover body and grate.
