303.06.0155 Complete, ALB Load Sensing Valve — SCANIA

This ALB Load Sensing Valve is a critical component within the pneumatic brake system of heavy commercial vehicles, designed to regulate braking force based on vehicle load. It ensures optimal braking performance by maintaining precise pressure differentials across its specialized ports. Built with heavy-duty grade materials, this unit provides reliable operation under demanding transport conditions.

303.06.0155 is the OE-equivalent of the WABCO 475 711 155 0 ALB Load Sensing Valve used in DAF, RENAULT TRUCKS, and SCANIA vehicles. This part meets strict technical requirements for compatibility with WABCO systems and other major heavy-duty vehicle manufacturers to ensure seamless integration into the braking architecture.

Workshop technicians should ensure all port connections are secure using the specified thread types: M22x1,5 Voss for Ports 1 and 2, and M16x1,5 Voss for Port 4. Regular inspection of the pressure thresholds—specifically the transition from empty to full pressure—is recommended during routine brake system maintenance to ensure the valve maintains its functional integrity and prevents system lag.
