Product Description
2.1
General
YT-3100 Smart Valve Positioner accurately controls valve stroke in response to an input signal of 4 ~
20 mA from the controller. Built-in micro-processor optimizes the positioner’s performance and
provides unique functions such as
Auto-Calibration, PID Control.

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.
➢
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.
➢
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 21 points characterizations.
➢
Tight Shut – Close and Shut - Open can be set.
➢
PID parameters can be adjusted in the field without any additional communicator.
➢
Split range 4 ~ 12 mA or 12 ~ 20 mA can be set.
➢
Operating temperature for positioners is -30 ~ 85 °C
(Please check certified explosion proof
temperature in case of Ambient temperature)
➢
Hand calibration function can set Zero point or End point manually.
➢
It has IP66 protection grade.
➢
Polyester powder coating resists the corrosion process.
➢
Maintenance of the positioner is easy because of modularized inner structure.
