Electric actuator QX series

rotaryDCAC

The Flowserve Limitorque QX, non-intrusive electric actuator is designed for a wide range of environmental applications in power, oil & gas, and water industries. The QX design builds on more than 20 years of proven MX technology to provide all the user-preferred features in a quarter-turn smart actuator package. Greater process control with non-contacting absolute encoders that provide accurate position sensing B.I.S.T., built-in self-test which never needs batteries to retain position data, even in the event of main power loss Extreme environment performance made possible by non-intrusive design, 100% solid-state controls, and reliable digital communication control system Versatility provided by flexible control configurations, setup and diagnostics in 11 languages, and advanced brush-less DC motor that supports most global voltages, AC or DC 100% repeatable and redundant absolute encoder for position sensing Electronic torque switch 3-phase, 1-phase, and DC motors Specifications All global explosion proof certifications Meets pertinent European Directives (CE mark) Designed to meet EN-15714 AWWA C540 Torque Rating Range: From 40 to 1500 ft-lbs output torque Non-intrusive, 100% solid-state, standard open-close applications Non-intrusive, 100% solid-state, modulating to 1800 starts per hour to EN 15714, Class D - Continuous duty Non-intrusive, 100% solid-state, network applications - Modbus, Foundation Fieldbus, HART, DeviceNet, Profibus DP w/ redundancy and Profibus PA
