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.

Floor type hydrostatic pressure relief valve shall be designed for installing in the bottom of concrete tanks. Cover body and grate. The groundwater pressure increase triggers the valve to open. 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. The assembly shall consist of three parts. Hydrostatic pressure relief valves ensure that concrete tanks don t float from the excess groundwater beneath them. Floor type model prf 15 and wall mounted model prb 14 hydrostatic pressure relief valves.

This unit incorporates the latest technology in combining metal and plastic for ultimate longevity and ease of installation. 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. They shall be designed so that neither the cover. 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.

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