✔ Confirm the two 3/8" supply ports, four 3/8" delivery ports, 3/8" control port, and 1/2" and 3/8" reservoir ports.
✔ Follow the approved RT-4 plumbing diagram and verify every port before disconnecting the original valve.
✔ Apply air-system-compatible thread sealant without allowing sealant to enter the valve.
✔ Remove protective port caps only when connecting clean air lines.
✔ Charge and leak-test the system, then verify reservoir protection and emergency spring brake application.
