Description
What does an air dryer valve do?
This air dryer valve plays a critical role in the pneumatic brake system by filtering out moisture and contaminants. By preventing water buildup, it protects downstream components from corrosion and prevents freeze-up during cold operations. This component is essential for maintaining consistent braking performance and long-term reliability in heavy commercial vehicle brake systems.Vehicle and system compatibility
This specific unit is compatible with MAN vehicles and meets the requirements of WABCO systems. It is engineered to operate effectively within high-pressure environments, ensuring that the air supplied to the braking circuit remains clean and dry.Technical specifications and installation
The valve is equipped with a 24 V heater to prevent moisture freezing in cold climates. Technical specifications include Port 1 and Port 21 measuring M22x1,5, with Port 22 and Port 4/23 utilizing M16x1,5 connections. It is rated for a pressure of 12,5 BAR to ensure stable operation under heavy loads.Maintenance and troubleshooting
To ensure optimal system health, technicians should inspect the valve during routine maintenance intervals. Checking for leaks or signs of moisture carryover can prevent more significant system failures. Consult your authorized distributor to check the compatibility list.OE cross-reference
