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.
