Replacement Air Compressor Spare Parts Valve 1619533811

Description：

Note that there is always a small hole in the air compressor unloader valve, so it will never close 100%. This is to make sure there will be enough oil flowing for lubrication and cooling.

Most unloaders are of the LOAD/UNLOAD type. Which means they are either completely open (compressor loaded) or completely closed (compressor unloaded). In unloaded state, when the unloader is closed, the unit will consume about 30% of it's nominal power.
