How to select a relief valveThe function of a relief valve is to help prevent an over pressure condition that could result in damage to downstream equipment. Typically, a pressure regulator reduces the supply pressure from the air compressorto a suitable working pressure. The relief valve is installed downstream of the regulator to protect downstream equipment from high pressure spikes.Flow capacity of the relief valve selected must equal or exceed the flow and pressure rating of the air compressor.

EXAMPLE:If your compressor delivers 47 dm3/s (100 scfm) at 12 bar (175 psi) and your system requires a working pressure of 6.2 bar (90 psi), the relief valve must have a set pressure slightly higher than the 6,2 bar (90 psi) working pressure and be capable of flowing 47 dm3/s (100 scfm) at 12 bar (175 psi), or pressures less than 12 bar (175 psi).
