EM57590

DASH VALVE 800523

The EM57590 is an aftermarket replacement for the Bendix MV-3 dash control module (Bendix p/n 800523). It is a two-button, push-pull manifold valve that controls the tractor and trailer parking and emergency brakes on heavy-duty trucks with dual air brake systems. The valve manages air pressure to release or apply spring brakes and provides a trailer air supply override feature. It is commonly replaced when the original valve leaks air, fails to maintain pressure, or the control knobs stick or break.
