This series of intelligent electric valve actuators delivers reliable torque output from 50 to 1000N·m, with multiple control modes and flexible power configurations, making it the ideal choice for business buyers in industrial automation, valve control, and process regulation. With an integrated, compact design and IP67 protection rating, it adapts to complex and harsh on-site environments, solving core pain points such as low control accuracy, high maintenance costs, and poor compatibility for industrial users.

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.
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.
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.
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.

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.
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).
