In the world of industrial automation, multi-turn electric actuators are the workhorses behind the precise operation of gate valves, globe valves, and sluice gates. Unlike part-turn models, these actuators are designed to rotate through multiple revolutions to drive a valve stem from open to closed positions. At Hengchun Actuator, we manufacture professional-grade multi-turn solutions that combine extreme mechanical durability with cutting-edge intelligent control systems.
A multi-turn electric actuator is an electromechanical device that outputs torque through more than one full revolution. It is specifically engineered to handle the high-thrust and long-travel requirements of rising stem valves. These devices are indispensable in sectors like long-distance oil and gas pipelines, thermal power plants, and wastewater treatment facilities, where reliability in complex working conditions is non-negotiable.
With over 32 years of industry experience, Hengchun Actuator has refined the design of our CKD and multi-turn series to meet the highest global standards. Our manufacturing process utilizes DMG and Doosan CNC machining centers to ensure every gear and housing meets micron-level tolerances.
Our actuators provide a wide torque range, typically starting from 40 N.m up to 3,000 N.m in direct drive mode. When paired with our specialized multi-turn gearboxes, we can achieve output torques exceeding 50,000 N.m, making them suitable for the world's largest industrial valves.
Modern automation requires more than just movement; it requires data. Hengchun’s intelligent multi-turn actuators feature built-in non-intrusive settings, enabling configuration via infrared or Bluetooth without opening the housing. They support a variety of communication protocols, including:
Profibus-DP
Modbus RTU
Foundation Fieldbus (FF)
HART Communication
Safety is our priority. Our actuators are designed with an IP68 enclosure, ensuring they remain operational even if submerged under 20 meters of water for 96 hours. Furthermore, our explosion-proof (Ex d IIB/IIC T4) models are essential for petrochemical and offshore oil rigs where volatile gases are present.
Hengchun’s multi-turn solutions are the preferred choice for a variety of critical infrastructure projects:
Energy & Power: Controlling high-pressure steam valves in thermal and nuclear power plants.
Oil & Gas: Reliable operation for long-distance pipeline isolation valves and storage tank terminals.
Water Treatment: Managing large-scale sluice gates and water distribution networks.
Marine Engineering: Specialized marine-grade actuators for shipboard valve control.
As a national-level "Little Giant" enterprise in China, Hengchun Actuator provides more than just hardware. We offer a comprehensive service system covering the entire industrial chain. From initial technical consultation and custom OEM design to five-star after-sales service, we ensure your actuation systems maintain a maintenance-free life for over 30,000 operations.
