P.M.R. TT9071E-VRT3-160 W/THERMAL RELIEF

SKU: 4653

P.M.R. TT9071E-VRT3-160 W/THERMAL RELIEF is an unloader valve (P.M.R. TT9071E-VRT3-160) — the component that protects your pump every time you release the trigger, diverting flow into bypass instead of dead-heading the pump. The built-in thermal relief dumps heat-soaked bypass water before it can cook the pump seals — critical on machines that spend long stretches in bypass. Set the unloading pressure to your machine's rating and check it with a gauge; a mis-set unloader either spikes the system or starves the nozzle.
