Trailer steering valves
Trailer control valves regulate air flow between the towing vehicle and the trailer. They ensure stable pressure distribution and reliable synchronization of brake and suspension systems.
The trailer control valve plays a vital role in the air system of tractor-trailer combinations. It controls the air pressure sent from the truck to the trailer’s braking and auxiliary systems, ensuring both parts of the vehicle work together smoothly and safely.
These valves help synchronize braking and air suspension across both units, preventing delays or uneven pressure that can affect performance. In demanding transport conditions, their precision ensures maximum stability and braking efficiency.
When worn or damaged, the valve can cause pressure loss, delayed braking, or unbalanced suspension — posing serious safety risks. Regular inspection and timely replacement are key to safe and effective air control.
