The SIPART PS2 -the most widely used intelligent electro-pneumatic valve positioner for linear and rotary valve actuators- demonstrates the versatility and reliability that you’ve come to expect from Siemens. It also has the ability to improve control valve life and performance via the on-board advanced diagnostics. Siemens believes that valve diagnostics are essential to the proper operation of a valve and includes them with every SIPART PS2. Utilize these features to reduce the cost of shutdowns, valve maintenance and valve inefficiencies. Implement these features to provide predictive maintenance in the plant.
