RV-500 PRESSURE RELIEF 3/8MPT 1900-3500P

The pressure relief valve is a safety device on the pressure washer. When a pre-determined pressure is reached within the system, the valve opens and releases water into the atmoshpere, or back into the line. The pressure relief valve is normally a second line of safety defense when used in conjunction with an unloader. It can also be used as the sole pressure safety device when installed in an open gun system.
