The Midland Haldex KN34111 is a two-line manifold-style tractor protection valve designed to consolidate multiple brake control functions into a single unit. It incorporates tractor protection, two double check valves, a stoplight switch port, and a built-in quick release, which means it can replace up to four separate valves found on competitive systems. Port connections include a 3/8" NPT tractor emergency inlet, two 3/8" NPT foot control ports, one 3/8" NPT hand control port, one 1/4" NPT stop light switch port, and 1/2" NPT outlets for both trailer service and trailer emergency lines. OEM cross-reference number is N30162ME. Repair kit RN31BC is available separately. Call us to confirm proper fit for your application.
