Description

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by filtering out moisture and contaminants from the compressed air. By preventing water accumulation, it protects downstream components from corrosion and freezing, ensuring consistent braking performance for heavy commercial vehicles.

System compatibility and features

This component is engineered to be compatible with Knorr-Bremse systems. It is designed to handle operating pressures up to 12 BAR and features a 24 V heater to prevent moisture buildup in cold climates.

Installation and technical specifications

Installation should be performed by a workshop technician to ensure all port connections are secure. The unit utilizes M22x1.5 ports (Port 1 and Port 21) and M12x1.5 ports (Port 22 and Port 4/23) to integrate seamlessly into the existing air circuit.

Maintenance guidance

Regular inspection of the valve is recommended to prevent system failures caused by contaminated air. Consult your authorized distributor to ensure correct fitment for your specific application.
