A cross-reference listing means this part may be a suitable replacement for the listed part numbers. Always verify fitment before installation.
IMPORTANT INSTALLATION NOTES:
✔ Confirm the replacement valve has a nominal 0 PSI cracking pressure and the correct four-port configuration.
✔ Connect the control, reservoir, and two delivery lines to their designated ports according to the vehicle air-system schematic.
✔ Plug any unused auxiliary connections with approved air-brake fittings.
✔ Inspect the air lines and fittings for contamination, restrictions, corrosion, and leakage before installation.
✔ Pressurize the system and test service-brake application, release timing, balance, and air leakage before returning the vehicle to service.
