YEPEF — Yangzhou Electric Power Equipment Manufacture Co., Ltd. — belongs to China Energy Engineering Group and is a Siemens-licensed manufacturer and a national "Little Giant" enterprise. The intelligent electric actuator is YEPEF's flagship product line, in three output forms: intelligent linear-stroke, intelligent multi-turn, and intelligent stacked, with the 2SA8 series (2SA8011, 2SA8021, 2SA8041-GDA and other ratings) as the mainstay models, plus intelligent-modulating variable-frequency derivatives.

The official product images show the typical configuration of this series: an integrated electro-mechanical structure with an LCD display and red/yellow status indicator lights on the front; parameter setting and commissioning are done with an infrared setting tool without removing any covers. Local and remote operation are both supported, with valve-position feedback output.

The three output forms match different valves: intelligent linear-stroke types pair with linear-stroke control valves; intelligent multi-turn types pair with gate and globe valves that need multiple turns; intelligent stacked types use a stacked-module structure, making it easy to combine function modules as required.

Basic selection logic: choose linear-stroke or multi-turn by valve type first, then finalize the configuration by control duty (modulating / on-off), signal standards, and expansion needs. For selection and quotation of YEPEF intelligent actuators, feel free to contact us.
