The FSD-1001-12.5 / 25 Series Flameproof Electrical Actuators from SDTORK are compact and high-performance solutions designed for precise and reliable valve automation in hazardous and industrial environments. These actuators are specifically engineered for quarter-turn applications such as butterfly valves, ball valves, plug valves, and dampers, delivering torque outputs up to 125 Nm, 250 Nm.
Built with a rugged flameproof enclosure compliant with international standards, the actuator ensures safe operation in explosive atmospheres by preventing internal ignition from propagating outside. The aluminum alloy housing provides excellent strength, corrosion resistance, and long service life.
The actuator features a high-efficiency gear mechanism with self-locking capability, ensuring secure valve positioning even during power failure. Its squirrel-cage induction motor with thermal protection delivers stable and reliable performance under varying load conditions.
Equipped with limit switches, torque protection, and position indication, the actuator ensures accurate control and protection of both valve and system. Optional integration with automation systems enables seamless operation and control in modern industrial processes.
