Great for restarting at low pressure, this MTM Hydro BP91 Unloader with a ByPass Valve and Easy Starter is rated at 1500 PSI with a maximum flow of 8 GPM and a maximum temperature of 195 F.
Unloader Valves are the traffic directors of your pump and pressure regulator. They serve to direct the flow of water in a pressure washer system. When water stops flowing from the nozzle of a spray gun, the unloader valve redirects it for a safe pressure outlet. When the cleaner is in “bypass mode,” water that is not released by the spray gun is diverted back to the inlet side of the pressure pump. It then circulates through the pump and back to the inlet side of the unloader valve. Water is once again either released via the spray gun, or redirected to the pump.
