Wolo Electric Solenoid Air Valves

5.0 out of 5 stars 2 Customer Reviews

Wolo electric solenoid air valves are available in several options to be used with air horns that have on-board air systems, as well as with all Wolo train horns. When the vehicle's horn button is pressed, the valve becomes electrically energized, opening the valve, permitting air to reach the horn. The solenoid remains engaged as long as the horn button is depressed. The valves have brass fittings making installation easy and leak-free, to 1/4 in. O.D. high-pressure air hose (hose not included).
