Description

What does an air dryer valve do?

This air dryer valve serves as a critical component within the pneumatic brake system, managing moisture and contaminants to protect downstream valves. Built with heavy-duty grade materials, it ensures long-term reliability under demanding transport conditions by maintaining clean air pressure throughout the system.

Vehicle and system compatibility

This component is specifically designed for use in Scania and Otokar vehicles. It is also compatible with WABCO systems, providing a high-performance alternative that maintains original equipment standards for fit and function.

Installation and maintenance guidance

Installation requires careful attention to the port configurations, specifically the M22x1.5 and M12x1.5 connections. Technicians should verify that the 24V heater is correctly integrated to prevent moisture buildup during cold operations. Regular inspection of the pressure levels at 7.3 BAR is recommended to ensure optimal system performance.

System troubleshooting

To prevent air system corrosion, it is essential to check the valve during routine maintenance intervals. Ensuring the integrity of this valve helps reduce wear on other pneumatic components in the vehicle's braking circuit.
