• 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 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
