Description

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by removing moisture, oil, and particulates from the compressed air supply. By ensuring a consistent flow of dry air, it prevents corrosion and extends the service life of downstream braking components. Built with high-strength components, it is designed to withstand demanding heavy-duty operating conditions.

Vehicle and engine compatibility

The unit is engineered for compatibility with DAF, Scania, Iveco, and Karosa vehicles. It functions effectively within systems requiring 24V electrical integration and specific pressure ratings up to 12.5 BAR. This part serves as a reliable replacement for units used in heavy commercial vehicle fleets.

Installation and maintenance

Installation requires careful attention to the M22x1.5 and M12x1.5 port connections to ensure a leak-free seal. Technicians should verify the 24V heater connection and ensure all lines are clear of debris during the replacement process to maintain optimal pneumatic performance.

System reliability

Regular inspection of the valve and its associated filtration elements helps prevent system contamination. Maintaining clean air through this valve ensures that the entire braking system operates safely under various load conditions.

OE cross-reference
