Description

The VADEN ORIGINAL 303.02.0044 is a precision-engineered component designed for reliability within the pneumatic braking system of heavy commercial vehicles. This high-strength component ensures stable air distribution across multiple circuits, maintaining system integrity even under demanding operating conditions.

This product serves as a high-quality replacement for the KNORR-BREMSE AE4616 and II36150 models. It is specifically engineered to be compatible with KNORR-BREMSE systems and features a robust design with Port 1 (M22x1,5) and multiple M16x1,5 ports for precise connectivity. The 303.02.0044 is the OE equivalent of the KNORR-BREMSE AE4616 and II36150 used in professional heavy-duty vehicle applications.<

For workshop technicians performing routine maintenance or system repairs, this valve provides predictable opening and closing pressure thresholds. With an operating pressure of up to 12 BAR and a maximum capacity of 20 BAR, it offers consistent performance in complex brake circuits. Always ensure that the connection ports are inspected for any debris before installation to maintain optimal pneumatic flow.

Maintaining the correct pressure settings is vital for vehicle safety and system longevity. This part is designed to handle high-pressure environments while ensuring that the individual circuit thresholds are met precisely as specified by the technical data.
