AWE - Model PRF Series -Groundwater Hydrostatic Pressure Relief Valves

AWE offers a range of Hydrostatic Pressure Relief Valves for applications where it is necessary to equalise pressure differential between external groundwater and internal tank levels to prevent floatation and excessive base slab loading. External groundwater pressure automatically opens the valve allowing the pressure exerted on the tank to balance with the internal pressure. The valves are commonly cast into the floor base slabs of concrete tank structures. However, side wall mounted versions are available to be installed at the bottom of tank walls.
