Description

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by managing moisture and contaminants within the air lines. By ensuring clean, dry air flows through the system, it protects vital brake components from internal corrosion and prevents freeze-up during cold operation. This component is manufactured using high-strength components to withstand heavy-duty operating conditions.

Vehicle and system compatibility

This part is specifically designed for DAF trucks and is also compatible with Knorr-Bremse systems. It features a 24 V heater to prevent moisture accumulation and utilizes M22x1.5 and M16x1.5 port sizes to ensure seamless integration into existing pneumatic circuits.

Installation and maintenance

For optimal performance, technicians should verify the port sizes (M22x1.5 and M16x1.5) and the 9.8 BAR pressure rating during installation. Regular inspection of the valve assembly helps maintain consistent braking pressure and prevents system-wide contamination.

Troubleshooting and selection

Consult your authorized distributor.
