Description
The braking system requires precise pressure management to ensure safety and reliability during heavy-duty operations. This 4-circuit protection valve is engineered to maintain optimal pneumatic stability across multiple circuits, providing critical control over pressure transitions within the pneumatic brake system.
The VADEN ORIGINAL 303.02.0068 is the OE equivalent of the KNORR-BREMSE AE4183 used in professional braking systems. This component features a specific configuration with Port 1 at M22x1,5 and multiple M16x1,5 ports (11, 12, 21, 22, 23, and 24) to meet exact technical requirements. It is designed to operate within a maximum pressure of 10 BAR, ensuring high-strength performance in demanding environments.
For maintenance professionals and workshop technicians, this valve offers reliable opening and closing pressure thresholds to ensure system integrity. The calibrated thresholds—such as the 7 BAR opening pressure for circuits 21 and 22, and the controlled closing pressures—make it a vital part for maintaining braking system efficiency.
This product is specifically designed for heavy commercial vehicle brake systems where precision is non-negotiable. Technicians should verify the specific port dimensions and pressure ratings to ensure perfect fitment during replacement.
