The Alltrux ATX6006 R-12 Relay Valve replaces OEM 102626 and is designed as a service replacement for heavy-duty truck air brake systems. It helps control and relay air pressure from the brake control valve to the service brake chambers, supporting faster brake response, consistent air delivery, and reliable braking performance in fleet and vocational environments.

R-12 relay valves play a critical role in air brake operation by reducing brake application lag and ensuring adequate air volume is delivered quickly to the brake chambers. As original relay valves wear internally, develop air leaks, or suffer contamination from moisture and debris, braking response and system efficiency can be negatively affected. Replacing worn relay valves helps restore proper air flow control, improve brake timing and balance, and reduce unplanned service events.
