The Bendix MV-3 Dash Control Module is a dual-button, push-pull valve that controls the tractor and trailer parking brake circuits from a single dash-mounted assembly. It consolidates tractor protection, trailer supply, and system park functions into one compact unit, replacing any existing two- or three-valve push-pull system with reduced plumbing complexity.

The MV-3 uses an integrated dual-circuit supply check valve to manage both primary and secondary reservoir connections, providing automatic trailer brake application if supply pressure drops to approximately 20-45 PSI, with a non-override trip piston activating at 20 PSI. The non-metallic, non-corrosive valve body has all air connections at the rear, with an optional auxiliary port available on select configurations.
