CAT Pump 7542 Unloader, 1/2", Brass, 21 Gallons Per Minute, 4000 PSI

This Pressure Sensitive Regulating Unloader is designed for single or multiple pump, weep or multi-nozzle systems. This unloader 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 cleared and minimal pressure fluctuation with the alternating use of multiple guns. 5-10% by-pass is necessary for optimum performance (blue spring).
