The YT-2700L is a digital electro-pneumatic positioner designed for linear control valves equipped with single-acting pneumatic actuators. It accepts a 4–20 mA DC input signal and modulates output air pressure to the actuator, ensuring valve travel matches the controller or DCS command. Supported features include auto calibration, PID/PD control, alarm functions, HART communication, and optional analog position feedback.
Compact datasheet specifies stroke 5–35 mm; series manual for YT-2700L states 10–150 mm. Confirm lever code and actual valve stroke before ordering.
Supports linear, quick open, equal percentage and custom 16-point characteristics. Split range 4–12 mA / 12–20 mA, tight shut-open/close, and variable orifice for hunting reduction on small actuators are available.
Suitable for control valves in steam, condensate, chilled water, hot water, instrument air, and auxiliary process lines, especially where compact mounting is required.
When to select YT-2700L?
When a compact smart positioner for single-acting actuators with HART or 4–20 mA feedback is required.
What should be checked before selection?
Stroke length, available air supply, actuator type, fail freeze/fail safe, HART, feedback, and Ex ia IIC T6/T5 requirements.
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.
