Model PS793

 

Overview


A pneumatic positioner based on the force balanced principle, designed for the proportional operation of quarter turn rotary actuators. It is generally coupled to the shaft of the actuator with a local visual indicator allowing easy on-site monitoring.

Designed for direct mounting to all NAMUR and Pentair Valves & Controls pneumatic actuators

 

  • Compact design – mounted directly and axially to the actuator stem by means of standard kit
  • Updated design provides improved features while maintaining original dimensions cam profile and product calibration
  • Captive fixings used throughout to prevent loss on site
  • High visibility, graduated local visual indicator disc allows easy on-site monitoring
  • Conduit boss is integral to enclosure wall providing greater strength and reduced footprint
  • Indicator gives visual position of the final control element
  • Stable positioning characteristics provided for both small and large actuators
  • Action (direct or reverse) is easily reversed in the field by turning cam and reversing air connection
  • Usable for double-acting or single-acting service
  • Unaffected by normal supply pressure fluctuations
  • Integral electric limit switches option.
  • Optional adapter and bracket kit for NAMUR actuators (bracket kit sold separately)
