Understanding the Pressure Washer Unloader Valve
The pressure washer unloader valve is a crucial component of the pressure washer that helps regulate the pressure and flow of water. It ensures that the pressure washer operates efficiently and effectively by controlling the bypass flow of water when the trigger gun is released.
When the trigger gun is pulled, the unloader valve opens, allowing water to flow through the pressure washer’s pump, creating high pressure. However, when the trigger gun is released, the unloader valve closes, diverting the flow of water back to the inlet side of the pump. This prevents the pump from building up excessive pressure and potentially causing damage.
