Product Description

General
The YT-2500/2550/2501 series Smart Valve Positioner accurately regulates the stroke valve in response to
4 ~ 20mA input signal from the controller. Built-in micro processor optimizes position
supports and provides unique features such as Automatic Calibration, PD Control, and HART
Communication Protocol. Control Valve

Key Features and Functions

➢ When the input signal fails, Positioner fails the current stroke position without being present
enhancements. (Failed Failure Option)
➢ The LCD screen allows the user to activate the status positioner.
➢ The user will easily discuss the method of using 4 buttons because it works the same as all versions
interface firmware.
➢ Positioners operate normally. There are sudden changes in supply and / or high pressure
Vibrational environment.
➢ YT-2501 is stronger than high temperatures and the environment due to an increase
remote sensors and positioners.
➢ The Automatic Calibration Method is very simple.
➢ As a benefit of having very low air consumption, this can save additional costs
large scale plants.
➢ This is compatible with most controllers.
➢ Variable holes can be used to improve hunting and optimize operations
condition.
➢ Various information about positioners can be done by HART communication. (selection)
➢ The valve system becomes more stable by issuing analog feedback signals.
➢ Different valve characteristics can be adjusted - Linear, Fast Open, Same Percentage, and
Set Users which users can make 5 points or 18 characterizations.
➢ Tight Shut - Close and Close - Open can be set.
➢ PD parameters can be adjusted in the field without additional communicators.
➢ Split ranges of 4 ~ 12mA or 12 ~ 20mA can be adjusted.
➢ The temperature for the YT-2501 series remote sensor is -40 ~ 120 ℃.
The winning temperature for the positioner is -30 ~ 80 ℃
temperature)
➢ Manual calibration function.
➢ Has an IP66 protection level.
➢ Polyester powder coating resists corrosion. (except YT-2550)
➢ Easy position maintenance due to modulated internal structure.
