Truck mechanics and owners, this dual manifold dash valve is a direct replacement for your Volvo, Freightliner, Haldex, Keene, and Newstar trucks. It replaces part numbers KN20619, RKN20619, 20560009, 85123221, and 20523171. The dual-circuit design gives you independent control over both tractor and trailer brakes, which is crucial for safety and proper braking performance. The 3/8\ PTC port sizes match original equipment specifications, so installation is straightforward with no modifications needed. This isn't some cheap knockoff - it's built to the same quality standards as the original part, ensuring reliable performance under demanding conditions. Whether you're dealing with worn valves during routine maintenance or emergency repairs, this valve will get your braking system back to proper working order. Always double-check compatibility with your specific truck model before ordering, but if you need any of those part numbers, this is the genuine replacement that will restore your braking system to factory specifications.
