PMR ZWD3035G-VRT3-250 W/BYPASS & THERMAL RELIEF

SKU: 4949

PMR ZWD3035G-VRT3-250 W/BYPASS & THERMAL RELIEF is an unloader valve (P.M.R. ZWD3035G-VRT3-250) — the component that protects your pump every time you release the trigger, diverting flow into bypass instead of dead-heading the pump. The thermal relief vents heat-soaked water from bypass before seals cook — essential where long bypass runs happen. Bypass port returns the diverted flow to the inlet side of the pump. Use a gauge to set unloading pressure at your machine's rating — mis-set means pressure spikes or a starved nozzle.
