Key Features & Business Benefits for business Buyers


Robust Durability for Reduced Total Cost of Ownership

The actuator features an integral aluminum alloy die-cast box, H-class asynchronous motor, high-precision alloy gears with multiple heat treatments, and high-strength copper alloy worm gear. This rugged construction ensures long service life, minimal wear, and stable performance, significantly reducing unplanned downtime and maintenance costs for business bulk users. The worm gear structure with self-locking function adds an extra layer of safety, preventing position drift during power outages and avoiding production accidents.


Flexible Configuration & Wide Compatibility

This high torque electric actuator supports a full range of power supplies, including AC220V, AC380V, DC24V, DC220V, with customizable special voltages for unique project needs. It is compatible with switching signals, 4-20mA current signals, and 0-10VDC voltage signals, seamlessly integrating with most industrial control systems. This eliminates the need for additional conversion equipment, reducing procurement costs and simplifying on-site deployment for system integrators and EPC contractors.


Intelligent CNC & High-Precision Control

The highly integrated intelligent control module enables digital setting, digital tuning, real-time self-diagnosis, and high-precision positioning. All series are equipped with electronic and mechanical dual limit devices to prevent overtravel, ensuring accurate valve control. This intelligent design cuts down on manual commissioning time, improves process control accuracy, and supports remote monitoring, perfectly matching the needs of automated production lines.


Maintenance-Free & Easy Installation

With a waterproof, rust-proof design, the IP67 electric actuator requires no refueling or regular inspection, and supports 360° installation at any angle. This greatly reduces on-site installation labor costs and daily maintenance workload, making it suitable for large-scale projects with multiple installation points.

Operating Principle


The Smart Type Electric Actuator converts the rotational power of the H-class asynchronous motor into 90° rotary torque of the output shaft through a high-precision alloy gear transmission system and copper alloy worm gear mechanism, driving the opening, closing, or regulation of the matched valve. The built-in intelligent control module receives control signals from the central control system, compares them with the real-time valve position feedback signal, and adjusts the output shaft rotation accurately. The dual electronic and mechanical limit devices stop the actuator immediately when reaching the set stroke, preventing overtravel, while the self-locking worm gear structure locks the valve position reliably when power is cut off, ensuring stable and safe operation of the pipeline system.


Industry Applications


This industrial electric rotary actuator is widely used in core business industries including: Water & Wastewater Treatment (butterfly valve/ball valve control for pipelines), Oil & Gas (process pipeline regulation), Chemical Processing (corrosive medium valve control), Power Generation (auxiliary system valve actuation), HVAC & Building Automation, and Pharmaceutical & Food Processing (sanitary grade valve control).
