Siemens SIPART PS2 Valve Positioner

Siemens SIPART PS2 is a digital valve positioner for linear and part-turn actuators in industrial applications.

SIPART PS2 is a digital valve positioner used worldwide for linear and part-turn actuators in industrial applications.

SIPART PS100 is a compact digital valve positioner used for linear and part-turn actuators. It is reliable, easy to use and quick to commission.

SITRANS mobile IQ is a free app that provides easy access to your field devices. Commission, configure, and monitor instrumentation via Bluetooth.

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.

The SIPART PS2 is available with remote position detection or with remote control electronics.

The SIPART PS2 valve positioner with a separate remote position detection can be used for valves at difficult accessible locations or for particularly critical process conditions, such as extreme vibrations or temperatures, dust or water influences.

Control electronics require special protection in environmental conditions with high-energy radiation. The SIPART PS2 valve positioner provides the option for separate, remote control electronics that are fitted in a control cabinet, whereas the position detection system and the pneumatic unit remain on the valve.

SIPART PS2 meets Siemens EcoTech standards by minimizing environmental impact across its entire lifecycle. Download the Siemens EcoTech Profile for SIPART PS2 and learn more about the product’s relevant sustainability performance data.
