Hendrickson Rep Map

To deliver the ride quality and other benefits fleets and owner-operators expect, air suspension systems require precise air flow management - a key element perfected by Hendrickson's standard height control valve (HCV) and integral HCV with automatic dump valve.

Specified by OEMs on new vehicles or through the aftermarket, Hendrickson's HCVs offer a choice of superb designs to keep vehicles at the correct ride height. Using an advanced Shear-Sheild® design to ensure accurate air flow, Hendrickson HCVs deliver superior performance and durability. A precise, highly repeatable dead band and high air flow with a proportional response optimize ride height control to deliver superior ride quality, while prolonging air spring and shock absorber life.

Specifically designed and tested for optimum performance with Hendrickson air suspensions, our HCVs help maintain outstanding load stability over the road. 

Hendrickson's HCV with integral dump features a high-flow design for rapid exhaust to save drivers time and effort as they load, unload and get back on the road. The dump valve automatically discharges the air springs with the setting of the parking brake and begins to air up with the release of the brake. Integrating the dump function in the HCV eliminates components and simplifies plumbing maintenance and installation.
