AVAT Quarter-turn Electric Valve Actuator
Loading 3D View...
Product Overview
The part-turn electric actuator is specifically designed for valves such as ball valves and butterfly valves that require 90° quarter-turn operation. It fully inherits the excellent performance and intelligent features of the AVA series multi-turn actuators, and highly integrates all core components for direct 90° part-turn output into a single, compact integrated mechanical housing.
Key Features
Adopts large-scale digital integrated chips, featuring powerful functions and high precision.
Non-intrusive design: All parameters can be set via an infrared setting tool without removing the electrical case cover.
Historical data recording function: Real-time records various parameters during operation, including torque value, operating status, and alarm signals, stored in a timeline format.
Precision valve position measurement system with an 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-brightness OLED/LCD digital and identifier display window with easy-to-read content, enabling convenient observation of the actuator's valve position, torque, and function status. The unique backlight system ensures clear viewing and setting even at night.
Equipped with a dynamic braking device. The transmission sequence of its worm and worm gear drive mechanism is irreversible, providing reliable braking 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 a digital interface to enable digital networking.
