Air compressors that are powered by a gasoline diesel or even propane motor have unloader valves as well.
Air compressor unloader check valve.
On these types of air compressors the unloader valve is also now known as a throttle valve.
This fix my compressor website is focused on the do it yourself and small workshop air compressor and most of these are reciprocating type air compressors.

When the compressor tank pressure reaches the point where the electrically powered compressor.
It blows off the pressure inside the discharge pipe when the compressor stops there is another type of unloader valve which can be found at the inlet of rotary screw compressors also called inlet valve or loading valve.
Gas air compressor unloader check valve pilot combo w throttle control 8hp max.
As mentioned a check valve is also installed to prevent the whole tank from draining.
There are few components on an air compressor that can multi task quite like the piloted unloader valve.
Bigger compressors also have a big unloader valve which is placed beside the air compressor.
This big valve is further controlled by a small pilot valve.
When the air compressor is turned off by the pressure switch the unloader valve is also triggered.
This single component can activate an engine idle control divert air from the tank when it reaches the top pressure setting and can reduce oil consumption by equalizing pressure between the pump and check valve.
The piloted unloader valve.
Gasoline or diesel driven compressor unloader valves.
