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:
✔ Mount the valve horizontally with both delivery ports facing to the side.
✔ Confirm the two 3/4" supply, two 1/2" delivery, and 1/4" control connections.
✔ Install close to the rear brake chambers to minimize application and release delay.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the valve.
✔ Pressurize the system and verify 4.0 PSI crack pressure, balanced delivery, rapid release, and leak-free operation.
