eml100Woodward’s EML100 electric actuator provides high accuracy, closed loop position control for steam and gas turbine valves. The actuator positions a steam or fuel valve that requires a linear operator with a stroke length between 13 and 38 mm (0.5 and 1.5 inches). This linear electric actuator is driven by an off-actuator driver Woodward’s EM/LQ Digital Driver.

Electric actuators have many advantages over hydraulic and pneumatic actuators when applied on steam turbine control valves. Electric actuators have the same or better accuracy and response times as hydraulic or pneumatic actuators without the need for expensive piping or filtering systems.
