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.

Product Specification

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.
