Relief valve to be mounted on the high-pressure circuit: it opens and discharges water if the pressure exceeds the set value, to protect the pump, the hoses, and the user.
Adjustment: with the motor running and the spray gun closed, tighten the adjustment nut to the desired pressure (approximately 10% above operating pressure for pressures over 100 bar, 20% below), then lock the locknut. On a machine equipped with a bypass valve, adjust the relief valve first.
Manufacturer specifications: max pressure and flow rate according to model (see versions).
