AVA Multi-turn Electric Valve Actuator China Model

Adopts large-scale digital integrated chips, featuring powerful functions and high precision grade.

Non-intrusive design: All parameters can be set via an infrared setting tool without removing the electrical case cover.

Historical data recording function: During the operation of the actuator, it can real-time record various parameters including torque, operating status, and alarm signals, which are stored in a timeline format.

Precision valve position measurement system with a measurement accuracy of 0.5%.

Accurate torque measurement system: Obtains precise torque values by measuring the reaction force of the motor worm thrust through pressure sensors.

High-definition OLED digital and identifier display window with easy-to-read content, allowing convenient observation of the actuator's valve position, torque, and function status. The unique backlight system ensures clear observation and setting even at night.

Equipped with a dynamic braking device. The transmission sequence of its worm and worm gear drive mechanism is irreversible, thus providing reliable braking function to prevent motor coasting.

The reducer adopts a worm and worm gear structure, with compact design, precise manufacturing and assembly, and a large transmission ratio. The motor shaft and worm are independent of each other for quick replacement.

The electric actuator is equipped with multiple protection functions, including motor overheating protection, overcurrent protection, phase loss protection, valve jamming protection, torque protection, torque measurement, emergency shutdown (ESD) protection, and automatic inspection function.

Fieldbus function: Provides seamless interface with any main control system and communication protocol.
