Siemens SIPART PS2 Electropneumatic Valve Positioners
The most widely used intelligent positioner for linear and rotary actuators, Siemens SIPART® PS2 electropneumatic positioner is used to control their final control elements. The PS2 valve positioner offers reduced installation overheads, function expansion with low-cost option modules, and enhanced diagnostics.
With its wide range, and an infinitely adjustable 3- to 130-mm stroke range, SIPART PS2 can be directly integrated to modern actuators without pipe work and without additional overhead. And it can be used with even the smallest actuators because the fully integrated valve block comprehends external position signals, and makes SIPART PS2 a lot more compact.
Siemens' Integral Volume Booster mounts directly on a PS2 valve positioner, and directs a high volume air supply to the actuator. It's designed for pneumatic actuators that require high flow for fast stroking times. It can reproduce pneumatic signals in a 1:1 ratio for applications that demand increased flow capacity and a reduction in piping, all while maintaining small step accuracy. This eliminates the complex piping and additional fittings required with external volume booster devices, reducing material and labor costs as much as 60 percent.
