301.02.0081 Complete, Air Dryer Valve - VOLVO

The heavy-duty function of the air dryer valve is critical for maintaining clean, dry air within the pneumatic braking circuit. This complete assembly is engineered with high-strength components to ensure long-term reliability in demanding heavy commercial vehicle environments. By effectively managing moisture and pressure fluctuations, it protects the integrity of the entire braking system.

301.02.0081 is the OE-equivalent of the KASSBOHRER 82855490000, PACCAR 1528633, VOLVO 20410157, VOLVO 20553336, VOLVO 3951836, and WABCO 432 410 192 0 components used in heavy commercial vehicle systems. This part is designed for seamless compatibility with major systems including WABCO and various heavy-duty vehicle makes such as VOLVO and PACCAR.

Workshop technicians should note the specific port configurations: Port 1 and Port 21 utilize M22x1,5 threads, while Port 22 and Port 4/23 utilize M12x1,5 threads. The unit is designed for a 24 V heater system and operates at a pressure of 8,5 BAR. Regular inspection of the air dryer assembly and ensuring clean connections is recommended to maintain optimal pneumatic performance during service intervals.

Proper installation ensures that the air filtration process remains uninterrupted, preventing moisture from reaching sensitive brake components. This high-grade component supports the operational stability required for fleet management and heavy commercial vehicle maintenance.
