Product Description
YT-2300 Smart Valve Positioner controls valve stroke accurately according to input signal
of 4-20mA being input from controller. In addition, highly efficient microprocessing operator
built in the product performs various and powerful functions like Auto calibration, PID
control, Alarm and Hart protocol.

Features and functions
1. LCD equipped outside of product makes to check the positioner condition in the field
directly.
2. It endures severe vibration.
3. It is operated normally regardless of change of supply pressure during operation.
4. Auto calibration method is very simple.
5. It is easily equipped on small actuator because of its small size.
6. Air consumption is so small that operating cost in huge plants is decreased.
7. Because it can be used in low voltage (8.5V), there is no limitation in controller.
8. Variable orifice is applied and so in case of small actuator the hunting is controlled to
the optimum condition during operation.
9. Hart communication makes to process various information of valve and positioner.
10. Valve system is stable by outputting analog feedback signal.
11. The adjustment of Valve characteristics (Linear, Quick open, Equal percentage) is
available.
12. Specific flow control is available with setting 16 point at users' command.
13. Tight Shut-Close and Shut-Open can be set voluntarily.
14. PID parameters can easily adjusted in the field without additional communicator.
15. The pressure of Air filter regulator is sent to Actuator directly with using A/M switch.
16. Split range such as 4-20mA, 12-20mA is available.
17. Setting Zero and Span as partial section is available by Hand Calibration function.
18. The valve defect is easily checked because the valve can be operated voluntarily.
19. It has IP 66 protection grade.
20. Air filter regulator can be attached with the product with only one linear nipple
without extra piping.
21. Because of Epoxy polyester powder coating, it can be used for long period of time in
corrosive air.
22. Because of simple and modulized inner structure, maintenance is very easy.
