How Does a Pressure Washer Unloader Valve Work? (Answered

Dec 10, 2021 · A trapped pressure unloader valve reacts to changes in pressure. When the trigger on the spray gun is released, there will be an increase in pressure. This will cause the unloader valve to open sending the water back to the inlet side of the pump. A flow-actuated unloader also reacts to pressure. When the flow of water is stopped, there will be

VB130 (PA) - High pressure & drain cleaning accessories - SJP

Flow Actuated: Unloader valves respond to the interruption of water flow to the nozzle. These valves sense any decrease in flow from the valve to the spray gun and initiate the bypass loop in response. Unlike Trapped Pressure valves, no pressure is trapped, so no "kick back" occurs when water is re-released.

Unloader Valves vs. Regulator Valves: What's the Difference?

Inside the valve will be a piston and seat held down by a spring. The trapped pressure is greater than the spring force causing the piston to move and bypass fluid to flow. While this trapped pressure is maintained, the pump head pressure will be low. Once the valve is opened and the trapped pressure is released, the pump head pressure will return.
