Rotork YTC Smart valve positioner YT3301/3302

YT-3301 Smart positioner supplies remote functions and higher liabilities in high temperature and vibration environment. YT-2501 Smart Valve Positioner accurately controls valve stroke, according to an input signal of 4-20mA, which is being inputted from the controller. In addition, a built-in micro-processing operator optimizes the positioner’s performance and provides unique functions such as Auto calibration, PID control, Alarm, and Hart protocol.

Key Roles and Features 

  • In high temperature and vibration conditions, the YT-3301 remote positioner is better since it is divided into a feedback sensor and a positioner.
  • The LCD display allows users to monitor the status of the positioner. 
  • The approach of using buttons is easily understood by users since it functions the same in all versions of interfaces for the firmware. 
  • If an unusual circumstance such as momentary blackout occurs, our boot-time positioner takes just 0.5 seconds to decrease the valve travel, which therefore reduces the valve travel. Increase device security.
  • Also, sudden changes in supply pressure and/or high vibration conditions are usually controlled by Positioner.
  • The Auto Calibration method is very easy. 
  • As an advantage of having very low air consumption, in large scale plants may dramatically reduce operating costs.
  • It is compatible with most controllers.
  • Also in the field, orifices may be installed to minimize the incidence of hunting and optimize operating conditions.
  • HART communication (HART option) can process various positioner information.
  • By generating an analog feedback signal, the valve mechanism becomes more robust.
  • Linear, Quick-Open, Equal Percentage, and Custom, which can be defined by 18 points, can be modified for various valves.
  • Tight Shut-Close and Shut-Open can be configured.
  • Without an additional communicator, you can change the PID parameters in the field.
  • A/M switch can be used to direct supply air to the actuator or to manually operate the positioner or valve without any signal.
  • The 4~12mA or 12~20mA split range can be set.
  • The operating temperature for the YT-3301 sensor module is -40 120°C.
  • The positioner operating temperature is -30 85 °C or -40 85 °C (certified explosion-proof temperature please datasheet)
  • The hand calibration function can set Zero point or Endpoint manually.
  • It has an IP66, Type 4X(FM) protection grade.
  • Epoxy polyester powder coating resists the corrosion process.
  • Maintenance of the positioner is easy because of the modularized inner structure.
  • SIL2 certified.
