Floating tanks can lead to serious cracks and other major issues.
Floor type hydrostatic pressure relief valve.
Floor type hydrostatic pressure relief valve shall be designed for installing in the bottom of concrete tanks.
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.
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.
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.
The groundwater pressure increase triggers the valve to open.
They shall be designed so that neither the cover.
Cover body and grate.
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.
This unit incorporates the latest technology in combining metal and plastic for ultimate longevity and ease of installation.
When this condition occurs the hydrostatic pressure will open the cover of the valve allowing water to enter thereby equalizing pressure inside and outside.
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 the tank.
