Featuring 1/4" female NPT inlet threads and a preset operating pressure range of 145-175 PSI, it efficiently cycles compressors by actuating throttle controls or discharge valves. Its manual unloader lever and dual-port design provide versatile, reliable performance in tight spaces, making it an essential upgrade for professional-grade compressed air systems. ## Description Unloader pilot valves are used in compressed air systems to actuate another device using a pneumatic (air) signal. Unloader pilot 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 pilot valve opens and actuates another device (throttle control, discharge valve). At the load setting, the pilot valve closes and returns the compressor to normal operation.
