Multi-turn

REGADA multi-turn electric actuators are specially designed for use in nuclear power plants outside the hermetic zone, where maximum reliability, extended service life, and precise control of multi-turn valves are essential. These actuators are ideal for knife gate valves, wedge gate valves, soft-seated or metal-seated designs, and other critical valve types requiring multiple shaft rotations to fully open or close.

They are well-suited for secondary cooling circuits, regulation stations, pressure control systems, and water management, where reliable actuation and fail-safe operation are fundamental to safe nuclear plant performance.

STANDARD version – Designed for ON/OFF applications requiring full valve opening and closing
Nuclear-ready design – Optimized for auxiliary and regulatory processes outside the hermetic zone
Precision control of multi-turn valves – Ideal for valves requiring multiple rotations for full actuation
Certified for nuclear use – Compliant with IEC, IEEE, and other relevant nuclear safety standards
Resistance to extreme conditions – Built for environments with high temperatures, pressure fluctuations, and mechanical stress
Rugged mechanical design – High resistance to seismic shocks and vibrations
IP68-rated protection – Sealed against water, dust, and chemically aggressive substances common in secondary circuits
Seamless system integration – Fully compatible with modern automation and control platforms

With advanced control capabilities, nuclear-grade safety certification, and a durable, maintenance-friendly build, REGADA multi-turn actuators are the ideal solution for valve automation in nuclear applications outside the hermetic zone.
