Description

The technical function of this air dryer valve assembly is to remove moisture and contaminants from the compressed air stream, ensuring the pneumatic braking system operates without interference. Designed with a high-strength construction, it provides consistent performance under heavy-duty cycles within the brake system.

301.02.0078 is the OE equivalent of the WABCO 432 410 114 0 complete, air dryer valve used in MAN, SCANIA, ASHOK LEYLAND, NEOPLAN, and WABCO systems. This component is specifically engineered to match the precise requirements of the original equipment parts including MAN 81.52102-6118, 81.52102-6120, 81.52102-6122, 81.52102-9120, SCANIA 390854, and WABCO 432 410 114 0.

For the workshop technician, this unit features a 24 V heater and specialized port configurations (M22x1,5 VOSS and M16x1,5) to ensure a secure and leak-free assembly. It is essential to verify the pressure settings and port compatibility during installation to maintain optimal pneumatic system integrity and prevent moisture buildup in the air lines.

Regular inspection of the air dryer assembly is recommended during routine service intervals to ensure that the filtration efficiency remains high and the heater functions correctly in cold climates.
