Description
What does an air dryer valve do?
This air dryer valve plays a critical role in the pneumatic braking system by managing air flow and preventing moisture accumulation within the lines. Built with high-strength components, it ensures consistent pressure regulation and protects downstream components from contaminants and corrosion during heavy-duty operation.Compatible vehicles and systems
This component is specifically designed for Scania trucks and is compatible with WABCO systems. It maintains optimal performance across demanding transport conditions, ensuring the integrity of the air supply throughout the braking circuit.Installation and maintenance
For proper installation, technicians should verify the port sizes: Port 1 and Port 21 utilize M22x1.5 threads, while Port 22 and Port 4/23 feature M12x1.5 threads. Ensuring all connections are secure at the rated 8.5 BAR pressure is essential for preventing system leaks and maintaining service intervals.Troubleshooting guidance
Regular inspection of the valve ports and seals helps prevent moisture bypass and ensures long-term reliability in commercial vehicle fleets.OE cross-reference
301.02.0049 (Air Dryer Valve Air Dryer Valves) is the equivalent of the Scania and WABCO OE numbers. This part directly replaces Scania OE number 390854. It also replaces WABCO OE number 4324100780.Technical Specifications
