Specification of

YT-3300 Smart Valve Positioner accurately controls valve stroke, according to input signal of 4~20mA being delivered from controller.

  • Auto calibration
  • Auto/Manual switch
  • HART comunication
  • LCD display
  • PID control
  • 4 buttons for local control
  • Feedback signal
  • Limit switch
Main Features and Functions
➢ LCD display enables users to monitor the positioner status.
➢ User will easily understand the method of using 4 buttons because it work same in all versions of
firmware interfaces.
➢ When unexpected situation like momentary blackout happens, our positioner boot-time only take
0.5 second and this can minimize the travel of valve which consequentially increase the safety of
system.
➢ Positioner operates normally even there are sudden changes in supply pressure and / or high
vibration environment.
➢ YT-3301 remote positioner is stronger on high temperature and vibration environment because it
is separated into remote sensor and positioner.
➢ The method of Auto Calibration is very simple.
➢ As an advantage of having very low air consumption, It could greatly reduce operating costs in
large-scale plants.
➢ It is compatible with most of controllers.
➢ Orifices can be installed even in the field to minimize the hunting occurrence and optimize
operating conditions.
➢ Various information about positioner can be processed by HART communication (HART option)
➢ Valve system becomes more stable by outputting analog feedback signal.
➢ Different valve characteristics can be adjusted – Linear, Quick Open, Equal Percentage, and
User Set which user can make 5 or 18 points characterizations.
➢ Tight Shut – Close and Shut - Open can be set.
➢ PID parameters can be adjusted in the field without any additional communicator.
➢ A/M switch can be used to direct supply air to the actuator or to manually operate the positioner
or valve without any signal.
➢ Split range 4~12mA or 12~20mA can be set.
➢ Operating temperature for remote sensor of YT-3301 is -40 ~ 120℃.
Operating temperature for positioners is -30 ~ 85℃ or -40 ~ 85℃ (Please check certified
explosion proof temperature)
➢ Hand calibration function can set Zero point or End point manually.
➢ It has IP66, Type 4X(FM) protection grade.
