SD-3001 Series
SD-3001 Series
The SDTORK SD-3001 Series Multi-Turn Weatherproof Electrical Actuators are advanced, high-performance units engineered for precise and reliable automation of multi-turn industrial valves. Designed for demanding process environments, these actuators deliver consistent torque, accurate positioning, and dependable operation in both open-loop and closed-loop control systems.
Built using a modular “Building Block Principle”, the SD-3001 Series offers flexibility in configuration, allowing easy adaptation to different valve types, torque requirements, and control applications. This approach ensures simplified maintenance, faster serviceability, and long operational life.
Powered by a reversible induction motor, the actuator provides smooth multi-turn motion with high mechanical efficiency. Its rugged construction, combined with advanced switching and signaling mechanisms, ensures safe, reliable, and precise valve operation even under heavy-duty industrial conditions.
The SD-3001 Series is specifically designed for critical multi-turn applications, making it an ideal solution for industries where accuracy, durability, and operational safety are essential.
