Korea YTC YT3100 Electropneumatic valve positioner Straight stroke
Angle stroke double action
product description
Intelligent positioner YT-3100 not only according to the controller
or the central control room input 4-20MA DC current signal control
pneumatic control valve opening, but also control the operation of
high-performance microprocessor it is a highly reliable positioner,
can perform a variety of powerful functions, such as calibration
and PID optimal 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.

nstallation
➢ Any input or supply pressures to valve, actuator, and / or to
other related devices must be turned off.
➢ Use bypass valve or other supportive equipment to avoid entire
system “shut down”.
➢ Ensure there is no remaining pressure in the actuator.
➢ The positioner has a vent cover to exhaust internal air and drain
internal condensation water. When installing the positioner, make
sure the vent cover must be facing downward. Otherwise, the
condensation water could cause damages to PCB.
