Description
What does a multi-circuit protection valve do?
This multi-circuit protection valve plays a critical role in the pneumatic brake system of heavy commercial vehicles by dividing the air supply into independent circuits. By isolating different brake lines, it ensures that a leak in one circuit does not lead to a total loss of braking capability, maintaining safety during heavy-duty operation.Vehicle compatibility and fitment
The component is engineered for high-performance reliability and is compatible with Mercedes-Benz and Faun vehicles. It features precise technical specifications, including M22x1.5 ports and specific pressure regulation settings such as a 7.5 BAR opening pressure for ports 23/24 and a 9 BAR closing pressure for ports 21/22.Technical specifications and installation
For workshop technicians, correct installation is vital to ensure the pneumatic circuit functions according to OEM standards. When replacing this valve, technicians should verify the port sizes and ensure the pressure thresholds align with the vehicle's specific brake system requirements to maintain optimal stopping power.Maintenance guidance
Consult your authorized distributor to confirm exact fitment for your specific vehicle configuration.OE cross-reference
