Product Description
General
YT-2500/2550/2501 series Smart Valve Positioner accurately controls valve stroke in response to
an input signal of 4 ~ 20mA from the controller. The built-in micro-processor optimizes the positioner's
performance and provides unique functions such as Auto-Calibration, PD Control, and HART
Protocol Communications.
Main Features and Functions
➢ When the input signal fails, the Positioner keeps the current position of the valve stroke without any
additional device. (Fail Freeze option)
➢ LCD display enables users to monitor the positioner status.
➢ The user will easily understand the method of using 4 buttons because it works the same in all versions of
firmware interfaces.
➢ Positioner operates normally even there are sudden changes in supply pressure and / or high
vibration environment.
➢ YT-2501 is stronger on high temperature and vibration environment because it is separated into
remote sensor and positioner.
➢ 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.
➢ Variable orifices can be used to minimize the hunting occurrence and optimize operating
conditions.
➢ Various information about positioners can be processed by HART communication. (option)
➢ Valve system becomes more stable by analog feedback signal outputting.
➢ Different valve characteristics can be adjusted - Linear, Quick Open, Equal Percentage, and
User Set which user can make 5 points or 18 points characterizations.
➢ Tight Shut - Close and Shut - Open can be set.
➢ PD parameters can be adjusted in the field without any additional communicator.
➢ Split range 4 ~ 12mA or 12 ~ 20mA can be set.
➢ Operating temperature for the remote sensor of YT-2501 series is -40 ~ 120 ℃.
Operating temperature for positioners is -30 ~ 80 ℃ (Please check certified explosion proof
temperature)
➢ Hand calibration function can set Zero point or End point manually.
➢ It has IP66 protection grade.
➢ Polyester powder coating resists the corrosion process. (except YT-2550)
➢ Maintenance of the positioner is easy because of modularized inner structure.
