Description

This air dryer valve plays a critical role in the pneumatic brake system by removing moisture and contaminants from the compressed air supply. By preventing water accumulation, it protects downstream components from internal corrosion and prevents freeze-up during cold weather operation, ensuring consistent braking performance.

This component is compatible with Knorr-Bremse systems and is engineered to withstand heavy-duty service conditions. It features specific technical specifications including a 24 V heater to prevent icing and port sizes of M22x1.5, M22x1.5, M12x1.5, and M12x1.5 to ensure precise integration into the existing air circuit.

For workshop technicians, maintaining correct pressure levels up to 12.5 BAR is essential for optimal valve function. Regular inspection of the ports and the heating element ensures the air dryer continues to provide reliable protection against system contamination during long-haul operations.
