The Model 811-EV is the electric solenoid valve used with all Wolo train horns. Designed to easily thread into the horn’s air inlet, no special tools are required. The solenoid valve has a bright triple chrome finish and is ideal to work with any 12-24 volt electrical system. When the vehicle's horn button is depressed, the Model 811-EV becomes electrically energized, opening the valve, permitting air to enter the horn. The solenoid remains engaged as long as the horn button is depressed. The 811-EV has a brass fitting for connection to ¼” O.D. high-pressure air horse, (hose not included).
