170.DC4474

DOUBLE CHECK VALVE

A double check valve (also called a two-way check valve) that accepts air from two separate sources and delivers the higher-pressure signal to a single outlet while preventing backflow between the sources. It is commonly used in heavy-duty truck air brake systems to supply the trailer hand control valve from both the primary and secondary circuits. This Automann part is an aftermarket equivalent of the Freightliner/Norgren double check valve AI38000404474.
