Features & Benefits
Soft Positioning
The actuator decelerates softly before reaching end of travel positions. This reduces impact on the valve body from the actuator’s mechanical kinetic energy and extends valve service life.
Flexible Control Configuration
The product monitors more than 20 status signals, including open/closed end position, remote/local switchover, general fault alarm, etc. Any status can be transmitted to the system via any output channel through configuration settings.
Comprehensive Self-Diagnostics with Configurable Safety Parameter Operation
Featuring an integrated intelligent structure, the product provides independent self diagnosis to reliably identify faults and alarm events.

Applications
Power
Widely used on boiler, turbine, blower and other stations to precisely adjust medium parameters, realize valve regulation and emergency cut-off, and ensure stable and safe unit operation.
Chemical
Widely deployed in chemical plants, mainly for rapid valve cut-off, flow regulation and emergency safety shutoff.
Water Treatment
Applied in municipal and environmental projects, waterworks and sewage systems for valve on/off control, flow and liquid level regulation.
Case Studies
Chengdu Tianfu International Airport – Tianfu Airport Tank Farm Intelligent Transformation Project
The M Series actuator gear unit uses materials selected for low-temperature resistance and features IP68 ingress protection. Specialized low-temperature processing addresses the effects of low temperature on seals, lubricants, and bearings, suppressing low-temperature embrittlement. It is designed to withstand ambient temperatures of -50℃ and below, with the OEM-specified gear lubricant adapting to operating conditions down to -57℃.
