Description
This load sensing valve plays a critical role in the pneumatic brake system by modulating braking force based on the vehicle load. By regulating air pressure delivery, it ensures stable and safe braking performance across varying weight conditions. This component is manufactured using high-strength components to withstand demanding heavy commercial vehicle service conditions.
The valve is designed for integration with WABCO systems and maintains high operational precision. It features multiple connection points, including Port 1 (M16x1.5), Port 2 (M22x1.5), and specific pressure ports (41 and 42) with a 4.9 BAR specification, ensuring exact pneumatic response during deceleration.
For workshop technicians, maintaining correct thread integrity on ports like M12x1.5 and M16x1.5 is essential during installation to prevent air leaks. Regular inspection of the valve's response to load changes helps prevent brake fade or uneven braking across the axle.
Consult your authorized distributor.
