Air Pressure Control Switch Valve F/Horn Compressor Tank 12V 120-150 PSI

Air Pressure Control Switch Valve for Horn Compressor Tank

This 12V air pressure control switch valve manages the compressor on an air horn tank, cutting the compressor in and out between 120 and 150 PSI to keep air pressure steady on demand.

Overview

This 12V air pressure control switch valve is made to regulate a horn compressor tank by turning the compressor on at the low set point and off at the high set point. It keeps an air pressure control switch valve cycle consistent between 120 and 150 PSI so the tank stays charged for horns and other air accessories. It suits drivers, mechanics, and builders running onboard air systems who want a dependable pressure switch valve for a compressor tank.

Good To Know

Q: How do I know if my pressure switch is bad? A: A compressor that runs constantly without building pressure or never shuts off often points to a failed switch. Replacing the switch restores normal cut-in and cut-out control.

Q: Does the set range matter? A: Yes, the 120-150 PSI range must match your tank and compressor ratings. Confirm your system's safe working pressure before installing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
