Limitorque SMB nuclear actuator

The eight models in the SMB-series range offer rugged dependability from the smaller SMB-000 through the industry’s largest electric valve actuator, the SMB-5. An extensive selection of motors is available to suit various speed and voltage requirements. Optional controls include an integral reversing starter and control voltage transformer, a control station with pushbuttons for open/stop/close functions, position indicating lights, and Local/Off/Remote selector switch.
The SMB is well suited to applications involving gate and globe valves, sluice gates, and other applications where long-term, uncompromised, reliable operation is critical. Fully qualified SMB is the recognized veteran of the nuclear power industry. The SB, a high-speed, high-temperature version of the SMB, is also available.
