Description
This high-strength component serves as a critical part of the pneumatic brake system, ensuring stable air pressure and moisture removal to maintain braking efficiency. Designed for heavy commercial vehicle applications, it provides reliable service under demanding operating conditions.
The 301.03.0062 is the OE equivalent of the KNORR-BREMSE II19209 and II19209N50 air dryer valve used in MAN systems. It is also compatible with several other high-standard references including K017711, K017711N04, K023968, and LA8543. This unit is engineered to meet the precise specifications of the vehicle's air treatment system.
Technicians should note the specific port configurations: Port 1 and Port 21 feature M22x1,5 VOSS connections, while Port 22 utilizes M16x1,5 VOSS and Port 4/23 uses M12x1,5 VOSS. The system operates at a standard pressure of 12,5 BAR with a 24 V heater to prevent freezing during operation.
Regular inspection of the valve and port seals is recommended to ensure optimal pneumatic performance. When replacing this component, verify that all connection ports match the vehicle's original specifications to prevent air leaks or pressure drops in the braking circuit.
