STEYR Air Dryer Valve for Steyr Trucks

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by filtering moisture and contaminants from the compressed air. By preventing water accumulation, it protects downstream components from internal corrosion and the risk of freezing in cold climates. This ensures consistent air pressure delivery and maintains the long-term reliability of the entire braking circuit.

Vehicle compatibility and fitment

This component is specifically compatible with Steyr trucks. It is engineered to meet the rigorous requirements of heavy commercial vehicle service, providing a high-strength solution for maintaining air system integrity. Check the compatibility list.

Technical specifications

The unit is equipped with a 24 V heater to prevent moisture buildup during periods of inactivity. Technical specifications include Port 1 and Port 21 at M22x1,5, with Port 22 and Port 4/23 at M12x1,5. Operating at a pressure of 8,1 BAR, this valve ensures precise control within the pneumatic loop.

Maintenance and inspection

To ensure optimal performance, technicians should regularly inspect all port connections and check for any signs of moisture bypass. Maintaining correct port seating and electrical connections to the heater is essential for preventing system failures in heavy-duty applications.
