Description

This repair kit provides the necessary components to overhaul the 4-circuit protection valve, a critical component within the pneumatic brake system of heavy commercial vehicles. By replacing internal wear parts, the valve maintains its ability to distribute compressed air into independent circuits, ensuring that a leak in one area does not compromise the entire braking capability of the vehicle.

This kit is designed for use with Knorr-Bremse systems and other compatible pneumatic components. It allows technicians to renew the internal mechanisms without the need for a complete valve housing replacement, making it an efficient solution for maintaining fleet safety and performance.

During installation, workshop technicians should carefully inspect the valve housing for any signs of damage or excessive corrosion. Replacing seals, diaphragms, and springs according to manufacturer specifications ensures that the protection valve returns to its intended pressure response and reliability.

Consult your authorized distributor.
