Unloader valves are essential safety and pressure-control components for pressure washer systems. They direct water flow from the pump and help prevent dangerous pressure buildup when the spray gun is closed. When water is not being released through the nozzle, the unloader valve redirects flow back to the pump inlet or bypass line to protect the pump, hose, spray gun, and other system components.
This category includes trapped pressure unloaders and flow actuated unloaders. Trapped pressure unloaders respond to pressure buildup and are commonly used in many pressure cleaning systems, while flow actuated unloaders respond to changes in water flow and help reduce spray gun kickback.
Unloader valves help regulate system pressure, improve operator safety, and protect equipment from damage. They are commonly used for pressure washer repair, replacement, maintenance, and system upgrades in residential, commercial, and industrial cleaning applications.
