305.01.0001.01 Repair Kit for Multi-circuit Protection Valves

What does a multi-circuit protection valve repair kit do?

This multi-circuit protection valve repair kit is a complete replacement set prepared for overhauling the valve that manages several air lines from a single housing in the pneumatic brake circuit of heavy commercial vehicles. It provides the necessary components to renew the internal sealing and circuit separation without the need to replace the entire valve unit.

Compatible vehicles and engines

This kit is compatible with Ford Trucks Cargo series equipped with Ecotorq engines (7.3 and 9.0 Euro 5). It also fits various other heavy commercial vehicles including Scania, VDL, Solaris, Faun, DAF, Mercedes-Benz and Iveco. The kit is specifically designed for use in systems compatible with WABCO systems and Provia systems.

Maintenance and installation guidance

When performing maintenance, technicians should ensure all internal surfaces are clean and inspect the valve housing for any signs of cracks or excessive wear. Proper installation of the new diaphragm and O-rings ensures that pressure distribution between service and parking circuits remains stable under heavy loads.

System reliability and selection

Regular inspection of these components helps prevent air leaks that could compromise the entire pneumatic system. Check the compatibility list to ensure this kit matches the specific valve configuration in your vehicle.
