Relay Valve Remanufactured
Mack

The Remanufactured Relay Valve is a rebuilt control valve used in air brake systems to modulate service and load-sensing functions. Each unit undergoes a comprehensive refurbishment process, including cleaning, testing, reseating, and replacement of worn components to meet or exceed original specifications. A remanufactured valve delivers predictable braking performance, reduces the need for new-valve purchases, and supports cost-effective maintenance strategies for fleets with extensive air brake networks. The unit is tested to verify fast response, durable sealing, and consistent modulation under typical operating pressures. By restoring critical valve operation, it contributes to safer stopping distances and reliable trailer or tractor articulation. Source One Parts Center.
