Features:
The difference between an MV-2 and MV-3 is pretty simple just check to see how your buttons are mounted to the Valve if the buttons are mounted with a rolling pin you have an MV-2 Valve if they screw on you have an MV-3 Valve.
The MV3 dash control valve combines the functions of a PP-1 control valve and a PP-7 trailer supply valve into a unified device.
The MV3 dash valve is a two-button, push-pull control valve housed in a single body which includes a dual circuit supply valve and a check valve.
The MV3 dash air valve can duplicate the functions of any existing two or three-valve push-pull system and has the advantage of reduced plumbing.
