YT-2550 Smart Positioner

Brand: Rotork YTC
Request Information
The YT-2550 Smart Valve Positioner accurately controls valve stroke according to an input signal of 4–20 mA, which is being input from the controller.

In addition, the built-in microprocessing operator optimizes the positioner's performance and provides unique functions such as auto-calibration, PID control, alarm, and Hart protocol.
Features
  • Fail freeze function 
  • Near-zero air consumption level 
  • HART communication 
  • Auto calibration 
  • PD control 
  • 4 buttons for local control 
  • LCD display 
  • Feedback signal 
  • Limit switches
