Overview
Improve trailer stability and operational safety with the Trailer Dump Valve Assembly by Automann. This high-performance pneumatic valve is specifically designed for Hendrickson suspension systems to exhaust air from the air bags during loading and unloading. By dumping the air, this valve prevents "trailer walk," lowers the deck height for easier dock access, and provides a much more stable platform for forklifts and cargo movement.
Advanced Pneumatic Performance: The Trailer Dump Valve Assembly Advantage
The Trailer Dump Valve Assembly (Automann Part # 171.H754WF) features the only completely pneumatic pin-pull mechanism on the market, eliminating the need for complex mechanical linkages. Engineered to withstand the harshest environments, this assembly has been tested for reliable operation in temperatures as low as -40°F. Note: This kit is a comprehensive solution, arriving complete with all necessary air fittings, exhaust tubing, and mounting hardware for a fast and efficient installation.
As we continue to build the largest inventory of commercial trailer parts in Illinois, we prioritize pneumatic solutions that enhance driver productivity. This assembly is a direct professional-grade replacement for Hendrickson VS-25224. By automating the air exhaust process, it ensures the suspension is properly managed during high-stress loading cycles, preventing costly damage to equipment and improving overall fleet safety at the dock.
