Mi-T-M 8-0032 Unloader Valve Orange Spring
The Mi-T-M 8-0032 is an unloader valve with an orange spring designed for pneumatic systems. It fits Mi-T-M brand equipment and is specified for use with Grainger item 3WB72 and manufacturer model GC-3004-4MGH. This new component serves as a direct replacement part for compatible air compressor setups.
Thermals Noise and Power Draw in Normal Use
As a mechanical pneumatic valve, this part operates without electrical consumption or active cooling requirements. It functions passively within the compressed air circuit, contributing no additional heat or audible noise beyond standard system airflow. Normal operation relies solely on line pressure to actuate the spring-loaded mechanism.
Behaviour Under Sustained Load
The orange spring provides a defined pressure response during continuous compressor cycling. Under sustained demand, the valve repeatedly vents head pressure between cycles to reduce motor starting torque. Its mechanical design maintains consistent actuation without electrical components that could degrade under prolonged thermal stress.

Questions about this item
How do I install the Mi-T-M 8-0032 unloader valve on my GC-3004-4MGH compressor, and what step is often missed?
Thread the valve into the pump head port, torque to spec, then connect the pilot line to the pressure switch unloader port; the step often missed is pressurising the system and checking for leaks at both connections before returning the unit to service.
What maintenance or replacement will the orange spring inside this unloader valve need over time?
The orange spring sets the unload pressure; inspect it annually for fatigue or corrosion and replace the spring if the compressor fails to unload at the correct cut-out pressure or cycles erratically.
What limit appears first when this unloader valve runs continuously on a GC-3004-4MGH unit?
Sustained cycling heat can soften the orange spring, causing the unload pressure to drift lower than the 3004 model's intended setting and leading to short-cycling or inadequate head unloading.
