SD-3000 + FWG Series
SD-3000 + FWG Series
The SDTORK SD-3000 + FWG Series actuators are heavy-duty, electric-motor-driven gear-operated units designed for reliable and precise remote control of industrial valves and gate systems.
Integrated with a Supplementary Full Turn Worm Gearbox (FWG), this series is engineered to deliver enhanced torque transmission, smooth mechanical operation, and superior load-handling capability in demanding multi-turn applications.
Equipped with advanced switching and signaling devices, these actuators ensure dependable performance in both Open-Loop and Closed-Loop control systems used in industrial process automation.
Developed using the proven “Building Block Principle,” the SD-3000 + FWG Series maintains a standardized core design while allowing flexible configurations based on valve type, torque requirement, process parameters, and duty conditions.
This series is ideally suited for large gate valves and heavy-load applications where durability, torque multiplication, and operational safety are essential.
