FSD-1001 Series – Single / Three Phase Quarter-Turn Flameproof Stayput Electrical Actuators
FSD-1001 Series
The FSD-1001 Series from SDTORK Controls Pvt. Ltd. is a flameproof, high-performance quarter-turn electric actuator designed for precise, reliable valve and damper automation in hazardous and explosive environments.
Engineered to comply with IEC 60079-0:2011, IEC 60079-1:2014, and IEC 60529:2013, the FSD-1001 Series ensures superior explosion protection by containing any internal ignition and preventing flame propagation into the surrounding atmosphere.
Built from high-grade aluminium alloy, the actuator’s robust construction withstands the high internal pressure of explosions without structural damage, ensuring operator safety and operational reliability.
Designed for industrial applications where flammable gases, vapors, or dust are present, the FSD-1001 Series provides dependable performance, mechanical strength, and operational endurance even in the harshest field conditions.
