IMPORTANT INSTALLATION NOTES:
✔ Fully depressurize the air brake system before removing or installing the valve.
✔ Confirm one 3/8" control port, one 3/4" reservoir port, and four 3/8" delivery ports.
✔ Verify the application requires a 4.0 PSI crack pressure and nipple-mounted configuration.
✔ Apply air-system-compatible thread sealant sparingly and keep all valve passages clear of contamination.
✔ Pressurize the system and verify balanced brake application, release response, and no air leakage at every connection.
