Electric Solenoid (air valve) used with air horns that require an onboard air system for 12-volt vehicles. When the vehicle's horn button is depressed, the Solenoid becomes electrically energized, opening its chamber and permitting air pressure to reach the horn. The solenoid remains open and engaged as long as the horn button is depressed. 1/2" pipe thread inlet & outlet ports, made of solid brass. Ideal for many other applications.

Valve pressure: Up to 225 PSI air pressure.
