Description
A precision-engineered 4-circuit protection valve plays a critical role in maintaining pneumatic stability within the brake system of heavy commercial vehicles. This component ensures that air pressure is distributed accurately across multiple circuits, providing essential safety and control during operation in demanding environments.
The 303.02.0108 is the OE equivalent of the DAF 1525882, SCANIA 1444899, and WABCO 9347147320 parts used in DAF and SCANIA heavy-duty vehicles. It features a specialized port configuration with Port 1 at M22x1,5 and four auxiliary ports (21, 22, 23, 24) at M16x1,5 to maintain optimal system pressure distribution.
For workshop technicians performing routine maintenance or repairs, this valve offers precise pressure thresholds: Opening Pressures are set at 7,5 BAR for ports 21, 22, and 24 (with 8,5 BAR for port 23), while Closing Pressures are standardized at 5,5 BAR across all ports. These technical specifications ensure seamless integration with existing pneumatic architectures.
Regular inspection of the pneumatic circuits and the protection valve is recommended to ensure the vehicle's braking performance remains consistent. Always verify the compatibility of the port threads and pressure ratings before installation to ensure long-term reliability in the field.
