Description
A critical component in the pneumatic brake system, the 4-circuit protection valve ensures the stable distribution of air pressure across multiple circuits. This component is engineered to maintain system integrity by isolating pressure drops and ensuring that the vehicle's braking performance remains consistent under heavy-duty operating conditions.
The 303.02.0107 is the OE equivalent of the DAF ACHA001 used in DAF heavy commercial vehicles and is also compatible with WABCO 9347140110 systems. It features precise port specifications including Port 1: M22x1,5 and Ports 21, 22, 23, and 24 at M16x1,5 to match standard industrial requirements for reliable air distribution.
Technicians should verify the specific opening pressures during installation: Port 21 and 22 operate at 7,2 BAR, Port 23 at 7,7 BAR, and Port 24 at 7,3 BAR. The closing pressures are calibrated between 4,8 BAR and 5,5 BAR to ensure optimal safety cycles. Regular inspection of these pneumatic thresholds is recommended to maintain fleet safety standards.
This part is essential for maintaining the pneumatic stability of the braking system in heavy commercial vehicle applications.
