Rotork Positioners YT-3300 & YT-3400

Back to Latest News Page

Norman Equipment is excited to introduce Rotork’s YT-3300 and YT-3400 Smart Positioner product featuring torque motor technology with communications. Smart Positioners use a microprocessor to position the valve actuator while monitoring and recording data. They function similarly to an electro-pneumatic analogue-type positioners, except the electronic signal conversion is digital rather than analogue. Smart positioners are extremely accurate, use less air, and allow for online digital diagnostics.

Smart Positioners YT-3300 Design Features:

  • Auto calibration: Simple menu structure with options to auto calibrate all parameters or zero and end points only.
  • LCD Display: Alphanumeric digital display for process values and calibration.
  • Partial Stroke Test (PST): Fully adjustable Partial Stroke Test. All functionality can be performed and selected locally, through push buttons, or remotely with communication protocol.
  • Feedback signal: Analogue and Digital feedback signals with 4 to 20 mA, mechanical and proximity switch options (Limit switch options for YT-3300 and YT-3500 models).
  • PID control: Pre-calibrated and user configurable variables via front panel pushbutton menu.
  • Auto / Manual switch: Enables closed-loop automatic valve position control or manual positioning via the A/M switch. The manual mode is useful for troubleshooting, calibration, system testing, or as a manual bypass.
  • HART communication: Allows commands, position feedback, and diagnostics to be sent digitally over the current loop.
  • Front panel pushbuttons for configuration: 4 robust and positive acting pushbuttons for field configuration.
  • Remote Mounting Options (YT-3301 model): Remote sensor via cable to enable the positioner to be mounted away from extreme temperature. ?

Smart Positioners YT-3400 Design Features:

  • Explosion / Flameproof Housing: Global certification for Zone 1 and Division 1 installations.
  • Auto calibration: Simple menu structure with options to auto calibrate all parameters or zero and end points only.
  • LCD display: Alphanumeric digital display for process values and calibration.
  • Partial Stroke Test (PST): Fully adjustable Partial Stroke Test, with single or double set positions, all functionality can be performed and selected locally, through push buttons, or remotely with communication protocol.
  • Feedback signal: Analogue feedback signals with 4 to 20 mA, mechanical and transistor switch options.
  • Auto / Manual switch: Enables closed-loop automatic valve position control or manual mode is useful for troubleshooting, calibration, system testing, or as a manual bypass.
  • PID control: Pre-calibrated and user configurable variables via front panel pushbutton menu.
  • HART communication: Allows commands, position feedback and diagnostics to be sent digitally over the current loop.
  • Front panel pushbuttons for configuration: 4 robust and positive acting pushbuttons for field configuration.
