The Midland Haldex KN25120 is a shuttle-type two-way check valve designed for air brake systems where two independent circuits must control or supply a single downstream system. It carries four 1/4" NPT female ports - two inlets (A and B) and two outlets (C and D) - in a compact body measuring 4.25" long x 2.25" wide x 2.5" tall. The shuttle design allows whichever inlet circuit carries the higher pressure to take priority, preventing backflow into the lower-pressure source. Mount horizontally only, as required by the design. OEM cross-reference N20966M. Call us to confirm proper fit for your application.
