Sipart PS2 is currently the most widely used positioner for linear and part-turn actuators in a wide range of process industries. The proven all-round design has a particularly flexible stroke range and intelligent diagnostics and it communicates via Hart, Profibus PA, or Foundation Fieldbus. (Picture: Siemens)
Valve Positioners

Flexible in Any Position — Valve Positioners as Versatile Multi-Taskers

An extremely broad range of process applications requires field devices with a high degree of flexibility. Likewise, the issues of standardization and simple stock management are becoming increasingly important. And the devices must meet the normal everyday requirements: easy to operate and capable of being used universally, while requiring minimal time and cost for maintenance. So how does this apply to automated valves?
