Top 10 Pressure Washer Unloader Adjustment

The unloader valve diverts water flow into bypass when the trigger gun valve is closed. Unloaders may be designed to respond to either an increase in pressure or a change in flow. The unloader valve may also be used for variable pressure adjustment.

•  Optimized internal passages that guarantee reduced pressure loss.
•  Antirotation device of the piston positioned inside the valve and obtained by an hexagonal sector of the piston itself.
•  O-rings of the fittings positioned upstream to the thread : no risk of fittings ejected in case of overpressure.
•  Double feed connection.
•  Version with knob fitted with locknut for minimum working pressure adjustment.

1) The valve has been designed for a continuous use with water at a temperature of 60°C (140°F). It can work for short periods with water at the maximum temperature of 90°C (195°F).

2) When the valve is in bypass mode, this is the decrease of pressure that has to occur in the circuit downstream of the valve, in order that the valve can restore the working pressure in the system. The indicated figure is expressed as a percentage of the pressure setting (working pressure).

3) If the valve is fed through the lower inlet port, the maximum flow rate is 20 l/min. At gun closure, a pressure increase occurs in the circuit downstream of the valve. This pressure increase is used to activate the valve and discharge all the flow in bypass. The value of the pressure increase cannot be calculated. It depends on the correct setting of the valve (see PRESSURE ADJUSTMENT/SETTING) and on the layout of the system: flow rate, working pressure, length and characteristic of the tubes, closing time of the gun.
