Flexible in Any Position — Valve Positioners as Versatile Multi-Taskers
The standard version of the Sipart PS2 has comprehensive diagnostic functions. It delivers reliable diagnostics data via the positioner and its adjacent units, i.e. the valve and actuator. This allows users to take action at an early stage before a serious valve or actuator fault occurs, thus avoiding a plant shutdown. This is crucial, especially in the case of safety valves.
Typical diagnostic functions are:
- pneumatic leaks;
- stiff valves;
- stiction of the stuffing box;
- wear on the valve seat or plug;
- deposits or caking on the valve seat or plug;
- histograms, trends;
- temperature measurement, stroke counter, etc.
Through a regular partial stroke test or an additional solenoid valve test, the Sipart PS2 ensures that ESD (emergency shutdown) valves and open/close valves remain movable in emergencies.
Everything Is Covered
Plant constructors and operators could not wish for simpler stock management than that which is provided by the Sipart PS2 — because the product number of the standard device always stays the same. Regardless of whether for a linear or part-turn actuator, long or short strokes, control or open/close valves, manufacturer-specific actuators or applications with external sensors, additional diagnostic functions — everything is covered by the flexible all-rounder, the Sipart PS2. A single standard version provides comprehensive functionality, expandable modules, and wide range of available mounting kits.
