Benefits

SIPART PS2 positioners offer decisive advantages:
• Simple installation and automatic commissioning (self-adjustment of zero and span)
• Simple operation with
- Local operation (manual operation) and configuration of the
device using three buttons and a user-friendly two-line display
- Programming through SIMATIC PDM
• Very high-quality control thanks to an online adaptation procedure
• Negligible air consumption in stationary operation
• "Tight shut-off" function (ensures maximum positioning pressure on the valve seat)
• Numerous functions can be activated by simple configuring
(e.g. characteristic curves and limits)
• Extensive diagnostic functions for valve and actuator
• Only one device version for linear and part-turn actuators
• Few moving parts, hence insensitive to vibrations
• External non-contacting position sensor as option for extreme
ambient conditions
• "Intelligent solenoid valve": Partial Stroke Test and solenoid
valve function in a single device
• Partial Stroke Test e.g. for safety valves
• Can also be operated with natural gas

• SIL (Safety Integrity Level) 2
