Rotork YTC YT-1050 Linear/Rotary Electro Pneumatic Positioner

YT-1050, the Electro Pneumatic positioner is used for the operation of pneumatic valve actuators by means of an electrical controller or control system with an analog output signal of DC 4 to 20mA or split ranges.

For the operation of pneumatic valve actuators, the YT-1050 Electro Pneumatic Positioner is used by means of an 
electric controller or control system with an analog output signal of DC to 20mA or split ranges.
  • Simple zero and span adjustment
  • No resonance between 5-200Hz
  • Auto/Manual switch
  • RA v.s. DA action and 1/2 split range setting by simple adjustment.

Main Features and Functions of YT-1050 Electro Pneumatic Positioner:

  • 2 million life cycle guaranteed
  • Response time is very fast and accurate.
  • Simple part change can set 1/2 split range.
  • Low air consumption
  • Simple Direct / Reverse Action change.
  • Simple Zero & Span adjustment.
  • Easy feedback connection.
  • Internal options, such as position transmitter (PTM) and/or limit switch (L/S) is available (for non-explosion proof positioner – external options must be installed for explosion-proof positioner)
  • A/M switch can be used to direct supply air to the actuator or to manually operate the positioner or valve.

Application of Electro Pneumatic Positioner:

With rotary air actuators, electro pneumatic positioners are used to accurately position control valves used in throttling applications. 4-20mA input control signal is converted to proportional pneumatic output by these valve positioners. This output is fed to an air actuator which, combined with mechanical feedback, in turn, controls the location and flow of the valve.
