Definition

An unloader valve is a vital component of pressure washers. It helps regulate the pressure of water in the machine by redirecting the flow back into the pump when the trigger gun is released. This mechanism is essential for protecting the pump and other components from damage caused by excessive pressure buildup.

The unloader valve works by sensing the pressure in the water flow and adjusting the valve position accordingly. When the trigger gun is pressed, the valve is closed, and the water exits through the nozzle, creating high pressure. When the trigger is released, the valve opens, and the water flows back into the pump, reducing the pressure.

It’s important to ensure that the unloader valve is functioning correctly to prevent damage to the pressure washer and to have it periodically serviced by a professional.
