Product Description

22911A Pressure-Actuated Unloader with Yellow Spring

Buy the Giant 22911A model unloader at Kleen-Rite at a great low price! When no flow is going out the outlet port, all flow is diverted to the bypass port at virtually no pressure. The unloader is capable of handling one or more shut-off guns and should be run with no bypass (if the full flow from the pump is going through the unloader). It actuates at around 10% above the system pressure.
