301.02.0043 Compatible Air Dryer Valve

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by managing air quality and pressure regulation. By removing moisture and contaminants from the compressed air supply, it protects downstream components from corrosion and mechanical wear. Built with high-strength components, it ensures consistent performance under demanding operating conditions.

Vehicle and system compatibility

This component is designed for compatibility with DAF, MAN, Scania, Nissan Ud Truck, and Kögel vehicles. It is also compatible with WABCO systems. For optimal service life, ensure the unit is installed in vehicles requiring these specific port dimensions and electrical specifications.

Installation and technical specifications

The unit operates at a pressure of 10 BAR and utilizes a 24 V heater to prevent freezing in cold climates. Installation should be performed by a workshop technician to ensure all M22x1,5 and M12x1,5 connections are secure and leak-free. Regular inspection of the ports and electrical connections is recommended to maintain system integrity.

Maintenance and selection guidance

When replacing this valve, verify that the new unit matches the existing port sizes and voltage requirements to avoid system mismatching. Check the air lines for any signs of oil or excessive water to identify if further system cleaning is required.
