Bendix Brakes 800519 MV-3 Dash Control Valve

This two-button, push-pull control valve is 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.
