Specification of Rotork YT-2700 Smart Positioner Valve

YT-2700 Smart Valve Positioner accurately controls valve stroke, according to input signal of 4-20mA, which is being input from the controller. In addition, built-in micro-processing operator optimizes the positioner’s performance and provides unique functions such as Auto calibration, PID control, Alarm, and Hart protocol.

Product Description
General
YT-2700 Smart Valve Positioner accurately controls valve stroke in response to an input signal of
4~20mA from the controller. 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 Input signal fails, 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.
➢ User will easily understand the method of using 4 buttons because it work same in all versions of
firmware interfaces.
➢ 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.
➢ Variable orifices can be used to minimize the hunting occurrence and optimize operating
conditions.
➢ Various information about positioner can be processed by HART communication. (option)
➢ 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 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 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.
➢ Epoxy polyester powder coating resists the corrosion process.
➢ Maintenance of the positioner is easy because of modularized inner structure.
