UNLOADERS / REGULATORS
Compressor Unloader Valve
A compressor unloader valve is an important piece of the hydro excavation process because when the trigger on the gun is pressed, it diverts the water flow through the bypass to let the water out. They are internal parts of the system that controls the water flow and pressure. They activate when the trigger is pressed because they react to the change in water pressure and flow.
We carry three different compressor unloader valves that all operate at different PSI and GPM so you can pick the one that best fits your needs. The also offer a high-volume option for those more intense jobs.
All Ports 1/2" NPT-F - Max Volume 21 GPM - Max Pressure 4500 PSI - Max Temp 200F.
