EFMB-1/2/3 Series Intergral Type Small Quarter Turn Electric Actuator
The EOM series electric actuator is a type of motor that uses a multi-stage reduction gear, worm gear, and other mechanisms to generate rotational force. This force is then transmitted through the output shaft to switch valve devices by rotating them 90°. The actuator is mainly used to control the opening angle of valves, such as butterfly valves, ball valves, plug valves, etc. The EOM integral type has a torque range of 10-20000N.m, and the conventional electric actuator in the series operates without a clutch, making it durable and reliable. It has a stable stroke and effectively improves transfer efficiency.
