Description
This multi-circuit protection valve plays a critical role in the pneumatic brake system of heavy commercial vehicles. By managing air pressure across different circuits, it ensures that a leak in one line does not lead to a total loss of braking capability, maintaining essential safety standards during operation.
The component is designed to work within complex braking architectures and is compatible with Knorr-Bremse systems. It features specific pressure thresholds, such as an 8 BAR opening pressure for Port 24 and 7.5 BAR for Ports 21, 22, and 23, ensuring reliable circuit isolation.
For workshop technicians performing maintenance, checking the thread integrity of the M16x1,5 and M22x1,5 ports is essential during installation. Ensuring the closing pressure remains within the specified 6.5 BAR range is vital for the correct functional performance of the entire pneumatic circuit.
Consult your authorized distributor.
