301.02.0105 WABCO Complete, Air Dryer Valve

This high-strength component is designed to manage air drying processes within the pneumatic brake system, ensuring consistent pressure regulation and moisture removal. Engineered for durability, this complete air dryer valve provides essential stability to the air supply of heavy commercial vehicles under demanding operating conditions.

301.02.0105 is the OE-equivalent of the WABCO 432 413 002 0 and SCANIA 390854 air dryer valve used in MACK, SCANIA, VOLVO, and WABCO systems. This part is engineered to meet strict technical requirements for heavy-duty truck and bus applications to ensure seamless integration with existing pneumatic architectures.

For workshop technicians, this unit features a 24 V heater and specific port configurations including 1/2"-14 NPTF for primary ports and 1/4"-18 NPTF for secondary ports. It is designed to operate within a pressure range of 7,9 to 9 BAR. Regular inspection of the port seals and heater functionality is recommended during routine vehicle maintenance to ensure optimal system performance.

Maintaining precise pressure levels is vital for the longevity of the entire brake system. This component helps prevent moisture buildup that could lead to system failures, making it a critical part for fleet management and heavy commercial vehicle servicing.
