SIPART PS2 in compact design - one that masters everything.

Description

 
The SIPART PS2 has grown to become the most widely used positioner for linear and rotary actuators. Optionally available with Makrolon, aluminum, stainless or flameproof steel enclosure, the positioner is well-equipped for all ambient conditions. It has proved reliable in many valve control applications thanks to its diagnostics capability and extensive range of functions.

 

  • Optional pressure sensors: improved valve diagnosis and process parameter monitoring

  • Regular partial stroke tests: ensured movements of emergency shut-down (ESD) valves and other open/close valves in the event of an emergency

  • Fail in Place: the valve remains in its last position upon loss of electrical and/or pneumatic power

  • Fail Safe: the valve moves to the safety position; also suitable for SIL2 applications

  • Valve performance tests (VPT): immediate, on-site assessment of valve maintenance requirements

The unique Fast Open/Fast Close technology allows faster valve adjustment thanks to smart chamber pressure control.

Our all-rounder can do even more: together with the SIPART PS2 booster, it allows for fast control of large actuators. Due to direct mounting on the positioner, the manual piping requirements are reduced to a minimum.

The refined positioner gives you the best possible support as you digitalize your processes. Thanks to assessments using the Siemens valve monitoring app, SIPART PS2 provides you with end-to-end control and analysis options. As a result, you can plan and perform your maintenance activities predictively and flexibly adapt your service intervals to suit your requirements
