Description
This air dryer valve plays a critical role in the air brake system by removing moisture and contaminants from the compressed air. By preventing water buildup, it protects downstream pneumatic components from corrosion and freezing, ensuring consistent braking performance for heavy commercial vehicles.
This specific component is compatible with MAN vehicles. It is engineered to meet rigorous operating standards, featuring a 24 V heater to prevent ice formation in cold climates and specific port configurations including M22x1,5 and M12x1,5 threads to ensure a secure fit within the pneumatic circuit.
For optimal performance, technicians should verify that all port connections are clean and that the 8.1 BAR pressure regulation remains within the manufacturer's specified range. Regular inspection of the valve housing and electrical connections for the heater is recommended during routine brake system maintenance.
Consult your authorized distributor.
