301.02.0111 WABCO Compatible Complete, Air Dryer Valve

The complete air dryer valve is a critical component within the pneumatic braking system, responsible for removing moisture and contaminants from the compressed air supply. This high-strength component is engineered to maintain optimal pressure levels and ensure the longevity of downstream pneumatic components by preventing ice formation and corrosion within the brake circuit.

301.02.0111 is the OE-equivalent of the WABCO 432 413 009 0 complete, air dryer valve used in heavy commercial vehicle systems. This part is designed for precision fitment with WABCO hardware, featuring a 24 V heater and specific NPTF port configurations to meet rigorous industrial standards for heavy-duty operations.

For workshop technicians, this unit offers a seamless installation process thanks to its standardized port sizes (Port 1: 1/2"-14 NPTF, Port 21: 1/2"-14 NPTF, and Port 4/23: 1/4"-18 NPTF). Regular maintenance checks of the air dryer valve are essential to ensure the pressure remains within the specified 7,9 to 9 BAR range, preventing system failures during heavy-duty transport cycles.

Proper selection of this component ensures that the braking system remains responsive under varying environmental conditions. By utilizing high-grade materials, this valve provides stable performance for long-term service in professional workshop environments.
