Description
This high-strength component is an essential part of the pneumatic brake system designed to ensure stable pressure distribution across multiple circuits. It plays a critical role in maintaining system integrity during heavy-duty operation by managing air flow and protecting the braking function through precise pressure thresholds.
The VADEN ORIGINAL 303.02.0076 is the OE equivalent of the KNORR-BREMSE AE4177 used in KNORR-BREMSE systems. This product features a primary port of M22x1,5 and four secondary ports (Port 21 to Port 24) measuring M16x1,5 each. Each circuit is calibrated with an opening pressure of 7,9 BAR and a closing pressure of 6,4 BAR to ensure optimal performance.
For workshop technicians and fleet managers, this component offers reliable installation due to its standardized port sizes and robust construction. It is designed for seamless integration into existing pneumatic architectures where precise pressure regulation is required for safety.
Regular inspection of the valve's pressure thresholds and port integrity is recommended to ensure long-term reliability within the brake system.
