MV-3 Dual Circuit Air Brake Control Valve 800257

From the Manufacturer

Overview 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. Features • Material: Heavy Duty Polymer (EGC-Engineering Grade Composite) • Mounting: Horizontal • Mounting Holes: Unthreaded • Exhaust: 3/8" PTC • Supply(2): 3/8" PTC • Tractor Delivery: 3/8" PTC • Trailer Delivery: 3/8" PTC Important The difference between an MV-2 and MV-3 is determined by how the 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.
