The 52520 Air Suspension Valve utilizes Barksdale’s patented Shear-Seal® technology to accurately control suspension height in commercial truck cabin applications. Shear-Seal® has become the industry leader through superior performance and long life, even under the most demanding conditions. The Shear-Seal® advantage combined with enclosed housing enables high dirt/contamination resistance.

Barksdale height control valves feature proportional response for minimal air consumption near deadband and better driver comfort. At the same time, new stem-less cartridge fittings and tamper-resistant screws increase robustness in the field. The Barksdale valve’s compact design and two sets of mounting holes (M6 & M8) allow easy direct replacement and installation in current cab air suspension systems.
