The 52321 Air Suspension Valve utilizes Barksdale’s patented Shear-Seal® technology to accurately control suspension height in commercial and recreational vehicle applications. Shear-Seal® has become the industry leader through superior performance and long life, even under the most demanding conditions. Barksdale height control valves feature proportional response and are available in both low flow and high flow configurations. These features combine to minimize air consumption without the use of inaccurate and failure prone time delay elements found in competing products. Available push-to-connect fittings and single or dual bag ports allow for easy and fast installation. The Barksdale valve’s compact design and Barksdale’s ability to customize the product make it a perfect fit on any suspension.
