Model 22S Electronic Pressure Sustaining

Model 22S Electronic Pressure Sustaining

The Model 22S Electronic Pressure Sustaining/Back Pressure Valve provides user pressure control with extreme stability over a wide range of flow. Combining the advantages of simplicity and line pressure operation with the features of electronic control, the valve is able to interface with SCADA systems to provide remote control and programmable variable logic. The electronic feature allows for a wider range of operation, simplifying valve sizing. Typical examples include water transmission lines, water treatment plants and pump back pressure control.
