SAI/SARI

The SAI/SARI type range is designed for the automation of valves in nuclear power plants. SAI/SARI actuators are used inside containment and are qualified in compliance with IEEE 382-2006. The DBE resistant SAI/SARI actuators can take over safety functions under DBE conditions. Multi-turn actuators of SAI type range can be used for open-close duty and positioning duty. SARI actuators are designed for modulating duty.
