ST-280 UNLOADER 8GPM 4060PSI

SKU: 3710

ST-280 UNLOADER 8GPM 4060PSI is an unloader valve rated for 8 GPM, up to 4060 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.
