Description
What does a repair kit do?
This multi-circuit protection valve repair kit provides a comprehensive set of replacement components designed to overhaul the multi-circuit protection valve within a heavy commercial vehicle's pneumatic brake system. By renewing internal elements, this kit helps maintain the vital function of managing multiple air lines from a single housing, ensuring that even if a leak occurs in one circuit, the remaining braking and auxiliary circuits remain operational.Vehicle compatibility and application
The kit is compatible with DAF and Iveco vehicles, supporting the essential air distribution between the service brake, parking brake, and suspension systems. This allows workshop technicians to restore internal sealing and circuit separation effectively without the need to replace the entire valve assembly.Installation and maintenance guidance
For proper maintenance, technicians should inspect the internal diaphragms, O-rings, and seals during routine pneumatic system service. Replacing these components helps prevent pressure loss and ensures that the circuit prioritization remains accurate under heavy-duty operating conditions. Consult your authorized distributor for more information.OE cross-reference
