Remanufactured Relay Valve
Mack

This Remanufactured Relay Valve is a critical component in air brake systems, controlling when and how brake chambers are pressurized to slow or stop the vehicle. The reman process rebuilds worn internal components—seals, springs, and diaphragms—so the unit restores precise response times and stable brake sensitivity, delivering consistent braking performance across a range of loads and road conditions. By refurbishing rather than discarding, the part offers a cost-effective solution that maintains OEM-style performance without compromising safety. The valve is calibrated to ensure proper pressure modulation and quick reaction to pedal input, reducing asymmetrical braking and helping to maintain straight-line stopping. Its robust construction supports long service life in demanding environments such as construction sites, long-haul fleets, and mixed-terrain work. Easy installation with standard fittings minimizes downtime during replacement. For reliability and value in a braking system that demands precision, this remanufactured relay valve is a solid choice. Source One Parts Center.
