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
Parameterization via SIMATIC PDM
Very high-quality control thanks to an online adaptation procedure
Negligible air consumption in stationary operation
"Tight shut-off" function (ensures maximum actuating force on the valve seat)
"Fail in place" function: Current position is retained on failure of auxiliary electrical power and/or pneumatic failure (does not apply in conjunction with SIL). Example: For an actuator with a volume of 8 liters, the typical position stability of a SIPART PS2 with "Fail in Place" is 0.3% per hour.
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
Full Stroke Test, Multi Step Response Test, Valve Performance Test for performance and maintenance evaluation of the valve
Can also be operated with purified natural gas, carbon dioxide, nitrogen or noble gases
