DP002122 Compatible Air Dryer Valve

What does an air dryer valve do?

This air dryer valve plays a critical role in the pneumatic brake system by managing air quality and moisture levels. Constructed with high-strength components, it ensures the consistent delivery of clean, dry air to the braking circuit, which is essential for the safety and longevity of heavy commercial vehicle components.

Compatibility and technical specifications

The unit is specifically designed for Alexander Dennis vehicles. It features a 24 V heater to prevent moisture freezing in cold climates and includes precise port specifications, including M22x1.5 and M12x1.5 connections, to ensure a secure fit within the braking assembly.

Installation and maintenance guidance

During installation, technicians should verify the electrical connection by disabling the battery or relevant fuse to prevent shorts. It is vital to check that the 24 V heater matches the vehicle electrical system voltage and to inspect all seals to prevent air leaks within the pneumatic lines.

System performance and troubleshooting

Regular inspection of the valve helps prevent system contamination and ensures optimal pressure regulation throughout the braking cycle.
