FRY-WA Series IoT Micro Electric Quarter-Turn Actuator

OVERVIEW

The FRY-WA Series IoT Micro Electric Quarter-Turn Actuator is an ultra-compact, high-torque smart electric actuator newly developed by Tianjin Freya Automation Technology Co., Ltd. (FRY). Designed specifically for 90° rotational valves including ball valves, butterfly valves, and air dampers, it accurately performs on-off opening/closing and high-resolution continuous modulating control across modern process automation pipelines.

Featuring an ultra-small footprint that reduces volume by more than 1/3 compared to traditional actuators of identical torque rating, the FRY-WA series integrates universal AC220V/DC24V voltage compatibility, a high-efficiency brushless motor, PWM stepless speed adjustment, an intuitive OLED graphic interface, and Modbus RTU communication. It is widely applied across food and beverage processing, environmental water treatment, papermaking, fine chemicals, power utilities, HVAC, and smart agricultural automation systems.
