Floor Type Hydrostatic Pressure Relief Valve

Floating tanks can lead to serious cracks and other major issues.
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. 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. The waterman model prf 15 hydrostatic pressure relief valve is the newest in a series of effective floor relief valves. This unit incorporates the latest technology in combining metal and plastic for ultimate longevity and ease of installation.
Floor type hydrostatic pressure relief valve shall be designed for installing in the bottom of concrete tanks. Cover body and grate. 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 groundwater pressure increase triggers the valve to open.
Floor type model prf 15 and wall mounted model prb 14 hydrostatic pressure relief valves. They shall be designed so that neither the cover. Hydrostatic pressure relief valves ensure that concrete tanks don t float from the excess groundwater beneath them. All three parts shall be of cast iron conforming to astm specifications a 126 class b.
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 in treatment plants to keep empty tanks from fl oating from an excess of groundwater beneath them.
