How does a truck leveling valve work?

A truck leveling valve is a device that helps to maintain the proper ride height of a truck by automatically adjusting the air pressure in the suspension system. Here's how it works:
When the truck is loaded, the weight on the suspension system increases, causing the suspension to compress and the ride height to lower.
The truck leveling valve senses this change in ride height and activates to increase the air pressure in the suspension system.
As the air pressure increases, it causes the suspension to expand and the ride height to return to its original level.
The truck leveling valve continuously monitors the ride height and makes adjustments to the air pressure as needed to maintain the proper ride height.
In summary, a truck leveling valve works by using air pressure to automatically adjust the suspension system and maintain the proper ride height of the truck. This helps to improve handling, stability, and overall safety while driving.
