Description

This air dryer valve plays a critical role in the pneumatic brake system by removing moisture and contaminants from the compressed air. By preventing water buildup, it protects downstream components from corrosion and prevents freeze-up during cold operations, ensuring consistent braking performance.

This component is designed for MAN vehicles and is compatible with MAN systems. It features a 24 V heater to prevent moisture accumulation in the valve body and includes M22x1.5 and M12x1.5 port configurations to ensure proper integration into the existing air circuit.

Technicians should verify that the port sizes, such as the M22x1.5 connections, match the existing installation requirements. During maintenance, it is essential to check the valve's ability to purge moisture effectively to maintain optimal system pressure and protect the air brake system components.

Consult your authorized distributor.
