Product Description

Flow Sensitive Unloader

This General Pump YUB21405 flow sensitive pressure unloader is designed for single or multiple pump, weep or multi-nozzle systems. It has (2) 1/2" NPTF inlet ports, a 1/2" NPTF outlet port, and a 1/2" NPT-F bypass port. This quality pressure unloader can handle up to 21 GPM and 4500 PSI (Rated at 4050 at 21 GPM).

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.
