The YT-2500 series intelligent valve positioner is a device that controls the valve opening by receiving a 4~20mA current signal from a controller or control system. It features a built-in microprocessor capable of controlling valve position and performing powerful functions such as auto-tuning, PID control, and HART communication.

Features

• Equipped with a signal loss lock function.
• Near-zero air consumption in standby mode, significantly saving plant energy.
• An LCD screen is mounted externally, allowing on-site confirmation of the positioner's status.
• Various signals from the valve and positioner can be obtained via HART communication.
• A valve position output module can be added to feedback the valve opening.
• Flow characteristics such as linear, quick opening, and equal percentage can be arbitrarily set.
• PID parameters can be easily adjusted via buttons on the device, and special flow curves can be set using 16 points.
• Excellent protection rating (IP66).
