The AP pneumatic positioner combines smoothness and accuracy with convenience and simplicity of use. It provides unparalleled performance and real industrial robustness, easy calibration, and is well adapted to a whole range of valve and damper applications. AP options include high flow valves, direct mount or industry standard discrete mount housings, 4-20mA angle retransmit, limit switches, Clear Cone position indicator as well as I/P convertors. Below are 14 features that make the AP positioner a standout among all other valve positioners.
  1. Enclosure and Lid – robust die-cast metal with tough corrosion-resistant epoxy coating and O-ring sealing. Layout gives easy access to all adjustments on removal of lid.
  2. Spool Valve – highly reliable, all metal, 5 port proportional valve controls the air flow. Three versions, with different flowrates, are easily interchangeable.
  3. Carrier Plate Assembly – integrated assemblies carrying the feedback shaft and cam plus angle retransmit drive and pot (when specified). Easily removed for conversion or maintenance.
  4. Interchangable Port Plate – easily convertible for different flowrate options.
  5. Feedback Pot Drive – zero backlash, proven trouble free for life.
  6. Retransmit Pot – high quality conductive plastic servo–type with ball bearings. Proven long life and high precision.
  7. Actuator Interface – options include NAMUR standard, Kinetrol male square or Kinetrol direct mount female square. Quick external conversion allows bracket mounting to any rotary or linear actuator.
  8. Internal Angle Scale – with adjustable indicator for easy field calibration.
  9. Exhaust Snubber Screws – allow travel speed reduction down to 1/ 3 x full speed, independently in each direction, by screwing in to restrict exhaust air flow.
  10. Gauge Port – as standard.
  11. Span and Zero Adjustment – quick and easy thumbwheel setting with slotted locking screw.
  12. Feedback Cam – quick and easy reversal ( for rotational sense handing) or replacement (to change the response characteristic) of the cam is facilitated by a spring loaded retention device.
  13. Feedback Shaft – innovative collet connection permits quick – fit/release of the actuator interface and eliminates backlash.
  14. Airflow Changeover Block – allows selection of direction in which positioner moves (for direct mount models).
