Flow Control - Actuator

EOM2-9 series integration type quarter turn electric actuator

The EOM series electric actuator is a motor-driven device that uses a combination of multistage reduction gear, worm gear, and other mechanisms to rotate and switch the valve device in a 90° rotation form through the output shaft. This actuator is primarily used to drive and control the Angle travel valve opening for various valve-like applications, such as butterfly valves, ball valves, and plug valves. The EOM intelligent type offers a torque range of 100-20000N.m, while the conventional EOM series electric actuator operates without a clutch, ensuring durability and stability of the stroke. These features enhance the transfer efficiency and reliability of the actuator.
