YT-2500R Electro-Pneumatic Positioner (Fail Freeze)
YTC model YT-2500R is an electro-pneumatic Fail Freeze Positioner for use with a rotary valve actuator and is operated by an electrical controller or control system with an output signal of 4-20mA or split ranges. In addition, a highly efficient microprocessor operator performs various and powerful functions like auto-calibration, PID control, Alarm & Hart Protocol. It freezes in the valve’s last position when there is a failure in signal or air pressure
Features: Fail Freeze Function
Near zero air consumption
Various valve characteristics such as linear, quick open and
equal percentage are available as options.
PID parameters can be adjusted easily in the field by button.
