Description

The complete ALB load sensing valve serves a critical function in regulating brake pressure based on the vehicle's load weight, ensuring optimal braking performance and stability. This component is engineered with heavy-duty grade materials to withstand the rigorous pneumatic requirements of the heavy commercial vehicle brake system.

303.06.0112 is the OE-equivalent of the WABCO 475 711 145 0 and VOLVO 9958760 load sensing valves used in heavy-duty truck systems. This unit provides precise pressure modulation through its specialized ports, including M22x1,5 and M16x1,5 connections, to maintain consistent braking force across varying load conditions.

For workshop technicians performing maintenance or system overhauls, this part offers direct compatibility with WABCO and VOLVO pneumatic architectures. Proper installation ensures that the pressure thresholds—specifically the 1,75 BAR empty pressure and the 7,7 BAR full pressure specifications—are met accurately to maintain vehicle safety and regulatory compliance.

Maintaining the integrity of the brake system requires high-strength components that can handle fluctuating pressure cycles without degradation. This valve is designed to provide a reliable solution for fleet managers looking to maintain original equipment standards during routine service or technical repairs.
