Description
The VADEN ORIGINAL 301.03.0040 is a high-performance component designed for the brake system to ensure optimal pneumatic stability. This complete air dryer valve plays a critical role in removing moisture and contaminants from the compressed air stream, protecting the downstream pneumatic components from damage and ensuring consistent braking performance in heavy commercial vehicles.
This product is the OE equivalent of the KNORR-BREMSE II19209N50, II31475, LA6222, LA8254 and MAN 81521026037 used in heavy-duty systems. It is engineered for full compatibility with KNORR-BREMSE and MAN systems, providing a reliable solution for maintenance professionals and fleet managers looking for precision-engineered parts.
The technical specifications include a Port 1 of M22x1,5 and Port 21 of M22x1,5, along with Port 22 and Port 4/23 featuring M12x1,5 connections. It is designed to operate effectively at a pressure of 12,5 BAR. Technicians should ensure that all connections are secured according to standard pneumatic assembly procedures to maintain system integrity.
Regular inspection of the air dryer assembly is recommended to prevent moisture buildup in the braking system. For detailed technical guidance or to ensure exact fitment for your specific vehicle model, consult your authorized distributor.
