301.03.0008 Complete, Air Dryer Valve — KNORR-BREMSE

The technical function of this complete air dryer valve is to ensure the efficient removal of moisture and contaminants from the compressed air system, maintaining optimal pressure levels for heavy commercial vehicle braking systems. It is constructed with high-strength components to withstand rigorous industrial environments and ensure long-term operational stability.

This product is a direct OE-equivalent for the KNORR-BREMSE II19204, II19204181, II19204AT, II19204N04, II19205N50, K02274, and LA 8207 series, as well as the MAN 81.52102-6117 and 81.52102-9117 models. 301.03.0008 is the OE equivalent of the KNORR-BREMSE II19204 complete, air dryer valve used in MAN heavy commercial vehicles.

Workshop technicians should note the specific port configurations to ensure a seamless assembly process. The unit features a M22x1,5 Port 1 and a M22x1,5 VOSS Port 21, designed to operate at a standard pressure of 8,5 BAR. Proper maintenance involves regular inspection of the VOSS connections and port integrity to prevent pneumatic leaks within the braking circuit.

For optimal performance in heavy-duty applications, ensure all connections such as Port 22 (M16x1,5 VOSS) and Port 4/23 (M12x1,5) are torqued according to standard technical specifications to maintain system airtightness.
