For fifty years, Barksdale’s patented Shear-Seal design has been the valve of choice for applications requiring tight shut-off, low pressure drop, high flow rates, and long life. The Shear-Seal principle allows unmatched design versatility. It’s at the heart of our simple panel mount shut-off air valves and our custom engineered automated 10-port injection valves for gas turbines.

The Shear-Seal design passes dirt and debris though the sealing rings instead of across the sealing surface. The basic design feature not only reduces wear, it actually creates a lapping action between the sealing surfaces that results in a valve that “wears in” instead of “out.” In fact, continual use can actually “heal” small scratches in the sealing surface.

Solutions for all your level control and overfill protection problems.

Whatever your pressure sensing and monitoring needs, Barksdale has a pressure switch guaranteed to do the job.  Barksdale’s pressure switches come with a variety of third party approvals such as UL, CSA, and Cenelec and are designed to serve the entire industrial spectrum, from vacuum to 18,000 psi.

Barksdale pressure transducers and transmitters are compact, rugged, reliable, and EMI/RFI protected.
