Pressure Relief Valve

Model 106-RPS-8700A

The 106-RPS-8700A pressure relief valve, which is UL / FM labelled and listed, automatically relieves excess pressure in the fire protection system to discharge. The RPS series valves will also automatically modulate to relieve excess pump capacity during pump start up and shut down, allowing the pump to operate without causing surges.

These relief valves are based on the 106-PG or A106-PG main valves and come in complete range of sizes from 2 1/2 in / 65 mm to 8 in / 200 mm. In typical pressure relief application, the angle style A106-RPS-8700A is often the preferred selection.
