Siemens 760 Positioner Electropneumatic Valve Positioners

Siemens 760 positioner P/E valve positioners provide a cost-effective, universal approach to valve control. The basic pneumatic model 760P1 takes a 3-15 PSIG input, and provides split ranging, direct or reverse action, and single or double action without adding any accessories. With the addition of an I/P transducer, the positioner becomes electropneumatic (760E1), to support a 4-20 mA DC input.

The mechanical linkage and characterization cam are field-replaceable to configure the positioner for use with either a linear or rotary actuator. No additional parts are necessary to change between single- or double-acting actuators or direct and reverse action.

Advantages of Siemens 760 P/E Positioner

  • Universal design and choice of interchangeable NAMUR IEC 534-6 rectilinear VDI/VDE 3845 rotary mountings provide wide application flexibility
  • Double-acting or single-acting service and split ranging afford application versatility in a single unit
  • Non-interaction of the zero and span adjustments and CAMLOC™ cam locking mechanism significantly reduce the calibration and setup time
  • Modular design reduces inventory because it allows interchangeable spare parts
  • Comes standard with 3 cams-linear, quick opening, and equal % for application versatility
