Upgrading to digital, zero-bleed valve positioners from outdated electropneumatic ones can lead to considerable cost savings.
Digital/Zero Bleed valve positioners, such as the Siemens SIPART PS2, are a more precise and efficient alternative to traditional electropneumatic positioners. They require 90 percent less control gas to execute the same position signal and use closed-loop control with a 99 percent position and tight closing function for greater precision in valve positioning. The smart chamber pressure control feature ensures faster valve adjustment, and non-contacting integral pressure sensors monitor the control gas supply and valve chamber pressure. Additionally, the SIPART PS2’s integrated booster applications provide the same level of precision and speed for larger drives.
