Description

This specialized ALB Load Sensing Valve is an essential component within the pneumatic brake system of heavy commercial vehicles. It functions by regulating air pressure based on the vehicle's load, ensuring consistent braking performance and safety during transit. Built with heavy-duty grade materials, this part maintains structural integrity under varying operational pressures.

303.06.0043 is the OE-equivalent of the WABCO 475 711 012 0 load sensing valve used in MAN and NEOPLAN systems. This component is fully compatible with several high-standard references, including MAN 81.52161-6268, 81.52161-6325, and 81.52161-6328, as well as WABCO 475 711 012 0 systems.

For workshop technicians, this assembly offers precise port specifications: Empty Pressure Port 41/42 at 0,35 BAR, Empty Pressure Port 2 at 1,8 BAR, and Full Pressure Port 41/42 at 7,2 BAR. The installation requires careful attention to the M16x1,5 thread sizes to ensure a leak-free connection within the braking circuit and to maintain optimal system-wide pneumatic stability.
