SIEMENS Electropneumatic positioners

SIEMENS Electropneumatic positioners,the SIPART ® PS2 electro-pneumatic valve positioner is used to control the final control element of pneumatic linear or part-turn valve actuators. The electro-pneumatic valve positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to block the valve or to set a safety position. A binary input is present as standard in the basic device for this purpose.

The SIPART PS2 smart valve positioner is characterized by significant advantages compared to conventional devices, such as:

  • Only one device version for linear and part-turn valve actuators
  • Simple operation and programming using three keys and a two-line LCD
  • Automatic startup function with self-adjustment of zero and span
  • Manual operation without additional equipment
  • Selectable or freely-programmable characteristics
  • Minimum air consumption
  • Selectable setpoint and manipulated variable limiting
  • Programmable “tight shut-off function”
