Service Tip
When installing this unloader valve make sure to torque the mounting bolts to the correct specs. The top outlet bolt should be torqued to 265in/lbs, and the bottom inlet bolt should be torqued to 354in/lbs.
Your typical regulating unloader valve functions as a safety device in which the regulating unloader valves control the direction of the flow of water exiting the pump. A positive displacement pump always delivers water, regardless of whether the spray gun attachment is in the open or closed position. When the spray gun is in the closed position the regulating unloader valve redirects the flow of water back through the By-Pass of the unloader and back to the inlet side of the pump. This prevents the excess buildup of high pressure and guards against the failure of component parts. Most pressure washers and carpet cleaners are installed with either a Trapped Pressure Unloader or a Flow Actuated Unloader.
