303.16.0015.02 Repair Kit for Park Release Emergency Valves

What is a park release emergency valve repair kit?

A park release emergency valve repair kit serves as a comprehensive replacement component set for rebuilding the parking and drain valve within a heavy commercial vehicle's pneumatic brake system. Instead of replacing the entire valve assembly, this kit allows for the renewal of internal elements to maintain optimal performance.

Vehicle and system compatibility

This component is compatible with Knorr-Bremse systems and is also fitted to Schmitz Cargobull vehicles. It ensures the valve can effectively convert commands into pneumatic signals, directing pressurized air to spring-type brake chambers or venting it from the system to ensure proper braking function.

Installation and maintenance guidance

When performing maintenance, technicians should verify the original valve manufacturer and model to ensure a precise fit. It is essential to check that the new gaskets, diaphragms, and seals match the original port count and connection thread size to prevent air leaks or stiff operation during use.

Troubleshooting and selection

To ensure correct operation, always inspect the valve body for any signs of debris or internal wear before installing the new kit components. Maintaining these parts helps safeguard the parking brake function and ensures correct system venting under heavy loads.
