ST-291 UNLOADER 5070 PSI

SKU: 6647

ST-291 UNLOADER 5070 PSI is an unloader valve rated up to 5070 PSI. When you release the spray-gun trigger, it diverts pump flow into bypass instead of dead-heading the pump — the valve that protects your pump and gives you trigger control. Size the unloader to your pump: its GPM range must cover your pump's flow, and its PSI rating must meet or exceed your system's maximum pressure.
