M-Series Intelligent Electric Actuators
Chongqing Chuanyi Automation Co., Ltd. (SIC)
1. Product Overview
The M-Series intelligent electric actuators are high-performance control devices designed for a wide range of industrial applications, including nuclear power, oil & gas, metallurgy, chemical processing, and water treatment.
These actuators incorporate advanced Variable Frequency Control (VFC) technology, enabling precise adjustment of speed, direction, and torque to achieve optimal valve control performance.
Key Technical Features:
-
User-Friendly Interface
All parameters can be configured via local pushbuttons and an LCD display without opening the housing or performing mechanical adjustments. -
Digital Position Detection
High-resolution digital encoders provide accurate measurement of position, direction, and speed, with no influence from ambient temperature. -
Electronic Torque Protection
Equipped with electronic torque sensing instead of traditional mechanical switches. Torque settings can be adjusted in 10% increments, effectively preventing motor damage during stall conditions. -
Integrated Variable Frequency Drive (VFD)
Built-in VFD enables soft-start and soft-stop control, reducing mechanical stress on valves and extending service life. -
Fieldbus Communication Compatibility
Supports multiple communication protocols, including PROFIBUS DP/DPV1, HART, Modbus, and Foundation Fieldbus (FF).
