Pressure Relief Valve
Pressure relief valves are suitable for sub-grade concrete tanks of all
kinds. Outside water pressure forces the relief valve open and allows water
to enter the tank. This tends to control buoyancy of the tank and prevents
floating.
All valves furnished standard with neoprene seat mountings unless otherwise
specified. Alternate bronze seat mounting available on special order. Specify
length when ordering.
