Pressure and Vaccum Switches for Process Applications
SOR Pressure Switches
The SOR pressure switches in this catalog are suitable for a variety of process applications.
Basic models with standard wetted parts are normally suitable for air, oil, water and noncorrosive processes. See the Quick Selection
Guide on pages 4 and 5. Specific application requirements can normally be met by selecting optional components, such as switching elements, diaphragm systems and pressure ports. See How to Order on page 3. Certain applications may require customized specials.
