The SD-1001-40 / 50 Series Electrical Actuator is a robust, high-performance quarter-turn actuator designed for precise and reliable valve automation in demanding industrial environments. Engineered for applications such as ball valves, butterfly valves, plug valves, and dampers, this actuator delivers consistent torque output ranging from 400 Nm,500 Nm, making it ideal for heavy-duty operations.
Built with a compact aluminum alloy housing, the actuator ensures durability, corrosion resistance, and long service life. The integrated self-locking gear mechanism maintains valve position without drift, enhancing operational safety and reliability. Its synchronous stall duty motor provides stable performance under varying load conditions, while the inbuilt thermal protection system safeguards against overheating.
The actuator is equipped with precision limit switches for accurate positioning and a mechanical position indicator for real-time status monitoring. In case of power failure, the manual override handwheel allows safe and easy operation.
Designed for harsh industrial conditions, the SD-1001 series offers IP65 / IP67 protection, ensuring resistance against dust, water, and environmental exposure. Its modulating, inching, and on-off control modes make it highly versatile for automation systems across industries.
