PID control YT-3700 single acting positioner Rotork smart Digital Valve Positioner with LCD display
YT-3700 / 3750 series Smart Valve Positioner accurately controls valve stroke in response to an input signal of 4~20mA from the controller. Built-in microprocessor optimizes the positioner’s performance and provides unique functions such as Auto-Calibration, PID Control, and HART Protocol Communications.

➢ LCD display enables users to monitor the positioner status.
➢ Users will easily understand the method of using 4 buttons because it works the same in all versions of firmware interfaces.
➢ When an unexpected situation like momentary blackout happens, our positioner boot-time only takes 0.5 seconds and this can minimize the travel of the valve which consequentially increases the safety of the system.
➢ Positioner operates normally even there are sudden changes in supply pressure and / or high vibration environment.
➢ YT-3301 remote positioner is stronger on a high temperature and vibration environment because it is separated into a 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 the 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)
➢ The 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 users 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.
➢ The operating temperature for remote sensor of YT-3301 is -40 ~ 120℃. Operating temperature for positioners is -30 ~ 85℃ or -40 ~ 85℃ (Please check the certified explosion-proof temperature)
➢ The hand calibration function can set Zero point or Endpoint manually.
➢ It has an IP66, Type 4X(FM) protection grade.
➢ Polyester powder coating resists the corrosion process. (except YT-3350).
