Description:

Unloader valves are used in compressed air systems to actuate another device using a pneumatic (air) signal. Unloader valves always work in conjunction with another device. Pilot valves operate in a set pressure range. The range has an unload setting and a load setting. As a compressor operates in this range, it is said to by cycling. At the unload setting, the valve opens and actuates another device (throttle control, discharge valve). At the load setting, the valve closes and returns the compressor to normal operation.
