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 trailer requires an SR-4-style valve with a 3/4"-14 NPT reservoir mounting connection.
✔ Match the 1/4" supply and service, four 3/8" delivery, two 1/4" reservoir, and 3/8" exhaust connections to the trailer schematic.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the valve passages.
✔ Mount the valve securely to the reservoir and confirm the exhaust dust shield remains unobstructed.
✔ Pressurize and leak-test the system, then verify reservoir protection, spring brake release, emergency application, and anti-compounding.
