Siemens Control Valves Positioner SIPART PS2
Summary:

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 - Parameterization via SIMATIC PDM

 

• Very high-quality control thanks to an online adaptation procedure                                          

 

•Negligible air consumption in stationary operation

 

• "Tight closing" 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 sensor as option for extreme ambient conditions

 

• "Intelligent solenoid valve": Partial Stroke Test and solenoid valve function in one device

 

• Partial Stroke Test e. g. for safety valves

 

• Can also be operated with purified natural gas,carbon dioxide, nitrogen or noble gases

 

• SIL (Safety Integrity Level) 2
