FPPK2507483 — Hadley Height Control Valve 171.H01501Udoe For Volvo Truck

This height control valve is a crucial pneumatic component that automatically adjusts the air suspension system on Volvo trucks to maintain a set ride height. It precisely regulates air pressure to the suspension air springs, ensuring a stable and comfortable ride, unlike a faulty valve which can lead to uneven suspension or excessive bouncing. Operators may notice the truck leaning to one side, a rougher ride than usual, or the suspension not returning to the correct level when this valve malfunctions.

Failure Symptoms

The first noticeable symptom of a failing height control valve is an uneven stance of the truck, with one side sitting lower than the other. If ignored, the suspension may continuously leak air, leading to a harsh ride and potential damage to air springs or other suspension components. This can compromise vehicle stability and driver comfort.

Installation Tip

Ensure all air lines are properly seated and secured to prevent air leaks after installation. Avoid overtightening the mounting bolts, which could distort the valve body.

Service Note

Inspect the air springs and air lines for leaks or damage when replacing the height control valve.
