1" UNLOADER VALVE 7592 CAT
This Pressure Sensitive Regulating Unloader Valve is designed for single or multiple pump, weep, or multi-nozzle systems. This unloader valve maintains set system pressure and goes into by-pass with the release of the trigger or an obstruction downstream. Pressure is held in the line during by-pass with full pressure when the gun is opened, or the obstruction is cleared and minimal pressure fluctuation with the alternating use of multiple guns. 5-10% by-pass is necessary for optimum performance. Minimum 10 GPM per gun.
