Description
The brake system relies on precise pressure regulation to ensure safety and stability during heavy-duty operation. This component serves as a critical control element within the pneumatic circuit, managing air distribution across multiple channels to maintain consistent pressure levels.
The VADEN ORIGINAL 303.02.0095 is the OE equivalent of the KNORRBREMSE AE4443 used in professional braking systems. It features a specialized port configuration including Port 1 (M22x1,5) and three M16x1,5 ports (Ports 21, 22, 23, and 24) to ensure exact fitment and reliable performance in heavy commercial vehicle pneumatic circuits.
Technicians can rely on the specific opening and closing pressure profiles of this valve to maintain optimal system integrity. The device operates with an opening pressure of 6,5 BAR for circuits 21 and 22, and 7,3 BAR for circuits 23 and 24, while ensuring a consistent closing pressure of 4,5 BAR across all outlets. This precision makes it an essential part for maintaining the pneumatic safety of the vehicle.
Regular inspection of the connection ports and pressure thresholds is recommended during routine maintenance to ensure the component continues to function within its design parameters.
