The MV-3 dash control module combines the functions of a PP-1 control valve and a PP-7 trailer supply valve together into one device. The module 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 MV-3 valve can duplicate the functions of any existing two or three valve push-pull system and has the advantage of reduced plumbing.
