It centralizes multi-circuit air management with smart prioritization and auto-draining, ensuring commercial vehicle braking reliability. Compared to discrete components, it saves 60% space and offers diagnostic ports for real-time pressure monitoring, ideal for new-energy commercial vehicles' high-integration requirements.

The port thread 21 to port thread 26 are all M22×1.5. The port thread 27 and port thread 28 are both M12×1.5. It is suitable for European trucks.
