Description
This specialized component is engineered to ensure reliable pneumatic control within the brake system of heavy commercial vehicles. Designed for high-performance stability, it manages pressure distribution across multiple circuits to maintain optimal safety standards during operation.
The VADEN ORIGINAL 303.02.0081 is the OE equivalent of the KNORR-BREMSE AE4187 used in KNORR-BREMSE systems. This part features a primary Port 1 of M22x1,5 and four secondary ports (21, 22, 23, and 24) of M16x1,5. Each circuit is calibrated with an opening pressure of 7 BAR and a closing pressure of 4,5 BAR to ensure precise pneumatic response.
For workshop technicians and fleet managers, this valve provides a robust solution for maintaining system integrity. It is essential for ensuring that pressure differentials are handled correctly within the braking architecture. When replacing worn components, verify that the port dimensions and pressure specifications match the original requirements to ensure seamless integration into the vehicle's pneumatic system.
