Product 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.
• Air compressor unloader control pilot valve for Air Compressor with 1/4" female threads on the bottom so it doesn't take up so much room in cramped spaces.
• The valve is used to operate a compressed air system at a constant run with a preset pressure operating range to actuate throttle controls, intake unloaders or air actuated discharge valves.
• The valves preset operating range is 145-175 PSI, it has 1/4" female NPT threads that would be used for air hook-up or screwed on to the compressor tank and has 1/8" female NPT threads on the side of the valve.
• Air inlet threads: 1/4" female NPT which measures about 1/2" in diameter with a ruler.
• Also equipped with manual unloader / control lever which is located at the top of the valve.
