Product catalog summary
Overview
Electric multi-turn actuators, specifically the SAN/SARN series by AUMA, are essential for automating valve operations in nuclear power plants, ensuring performance under Design Basis Event (DBE) conditions.
Electric multi-turn actuators, specifically the SAN/SARN series by AUMA, are essential for automating valve operations in nuclear power plants, ensuring performance under Design Basis Event (DBE) conditions.
Applications
The SAN and SARN actuators are used for valve automation requiring rotational movement and can be adapted for various tasks with AUMA valve gearboxes, extending torque ranges and converting actuators into part-turn or linear actuators.
