Description
This air dryer valve plays a critical role in maintaining the integrity of the pneumatic brake system by effectively managing air quality. By removing moisture and contaminants from the compressed air, it protects downstream components from internal corrosion and prevents freeze-up risks during operation. High-strength components ensure the valve withstands the rigorous demands of heavy commercial vehicle service life.
This component is specifically designed for MAN vehicles and is also compatible with WABCO systems. It features a 24 V heater to prevent icing in cold climates, a maximum operating pressure of 12.5 BAR, and specific port configurations including M22x1.5 VOSS (Port 1 and Port 21), M16x1.5 (Port 4/23), and M16x1.5 VOSS (Port 22).
For professional workshop technicians, ensuring correct installation is vital for pneumatic system health. Check all connection points, such as the M22x1.5 VOSS ports, to prevent air leaks and ensure the 24 V heater is properly wired to maintain optimal operating temperatures. Regular inspection of these valves helps prevent moisture-related failures in the braking circuit.
Consult your authorized distributor.
