SIEMENS VALVE POSITIONERS

Siemens Series PS2 Electropneumatic Positioners

Siemens Series PS2 Electropneumatic Positioners
The SIPART PS2 electropneumatic positioner is used to control the final control element of pneumatic linear or part-turn actuators. The electropneumatic positioner moves the actuator to a valve position corresponding to the setpoint. Additional function inputs can be used to block the valve or to set a safety position.

The PS2 is the state-of-the-art in valve positioners. Compatibility with HART, Fieldbus and Profibus is available. Partial stroke testing and advanced diagnostics are standard.

The PS2 is also a no-bleed device when in steady-state, and the PS2 can be operated with natural gas. No hand-held devices or calibrators are required. Any configuration and setup can be done through the integral interface. Rated SIL (Safety Integrity Level) 2.

Siemens Series 760PE Valve Positioners

Siemens Series 760P/E Valve Positioners
The Series 760 Valve Positioners provide a cost effective universal approach to your valve control. Their modular concept allows all models to be built on the base pneumatic unit (Model 760P). The electro-pneumatic model (Model 760E) is created by adding an I/P transducer to the base pneumatic unit, and a wide range of accessories easily installs inside the unit. The 760 base pneumatic unit provides cam characterization, split ranging, direct or reverse action, and single or double acting without requiring additional parts. Key design features include non-interaction of the zero and span adjustments.

Series 760 Valve Positioners include provisions for internal limit switch mounting and position feedback devices without requiring additional housings. Thus, the need to stack housings that impede access to the main enclosure are eliminated.
