Height Control Valve
Remember This

Hendrickson's non-delay Height Control Valve delivers twice the airflow of comparable sized valves for quicker air up, better response after dump and faster exhaust delivering greater stability during loading and unloading. The tuned dead band and porting minimizes air consumption while improving the overall suspension system response. Available with an integral air-dump feature.
