Main Features and Functions

  • LCD display enables users to monitor the positioner status.
  • Positioner operates normally during sudden changes in supply pressure and / or high vibration environment.
  • Low air consumption level and low voltage use (8.5 V) yield to lower plant operating costs. The YT-3400/3450 is compatible with most of controllers
  • Variable orifice can be used to minimize the hunting occurrence and optimize operating conditions.
  • Valve system feedback is greatly improved by the accuracy and fast response of the YT- 3400/3450.
  • Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and Custom which user can make 16 points characterizations.
  • Tight Shut – Close and Shut – Open can be set.
