Trusted across industries worldwide, the SIPART PS2 is Siemens' proven-in-use, smart electropneumatic positioner. Built for the most demanding environments, it auto-calibrates to your valve, minimizing commissioning time and delivers advanced diagnostics built in. Available in multiple enclosure options: polycarbonate, aluminum, stainless steel, and flameproof variants — ready for any installation requirement.
High reliability and product lifetime thanks to robust enclosures and modular design. Easy mounting, wiring and calibration for all common types of valves. Global certificates and marine approvals for worldwide usage.
Intelligent diagnostic features like partial stroke test, fail-in-place function, valve signature test, integrated pressure sensors, remote operation and many more.
Up to 95% lower operating costs due to extremely minimal compressed air consumption.

The SIPART PS2 can be operated remotely with the retrofittable SITRANS AW050 Bluetooth adapter and the free SITRANS mobile IQ app. This allows easy access to SIPART PS2 in difficult locations.
By simply retrofitting different modules for your specific positioner applications, you can achieve maximum flexibility for your plant.
The booster integrated in the positioner allows fast control of large drives and reduces external piping to a minimum.
The integrated fast open/fast close function enables rapid valve positioning thanks to intelligent chamber pressure control.
According to your needs, choose between fail safe, fail-to-open or fail-in-place function for maximum process stability and safety.
