CKDII Series
The CKDII Series Intelligent Multi-turn Electric Actuator is a cutting-edge industrial automation valve control device independently developed by Yangzhou Hengchun Electronics Co., Ltd., a leading China manufacturer of industrial actuators. Engineered with a high-precision worm gear transmission system, high-efficiency AC squirrel cage motor and integrated intelligent control unit, this electric actuator delivers zero-delay command response and ultra-stable operation for industrial valves. It is specially designed for gate valves, globe valves, diaphragm valves and slide valves, and features seamless integration with mainstream industrial control systems via multi-bus communication modules. With an IP68 protection rating and explosion-proof performance up to Exd II CT6, the CKDII Series excels in extreme working conditions, becoming a core component for safe and efficient industrial operation in power, petrochemical, metallurgy and marine engineering fields.
Equipped with a tempered glass window and innovative dual-screen display technology (dot matrix + segment display), it offers rich operational parameter visualization. A magnetoelectric multi-turn absolute position encoder with a 10,000-turn detection stroke ensures high-precision valve position sensing, and a smart battery management system maintains continuous valve position display during power failure.
The actuator provides 31 fault diagnosis functions (motor overheating, phase loss, over-torque alarm, etc.) and multiple preventive fault diagnosis features including temperature and torque trend analysis, enabling real-time monitoring of 10 types of status information for intelligent risk control.
It fully supports mainstream bus protocols (Autbus, Profibus-DP, Modbus, FF, Hart) and Bluetooth communication for wireless data interaction and program upgrade. The plug-and-play card design and anti-vibration circuit board bracket simplify on-site maintenance, while the dual-sealing structure enhances overall sealing performance and expands mechanical cavity for easy component installation.
