Flow Control - Actuator

EFMB1/A/B-H Series Integral Type Small Quarter Turn Electric Actuator

EOM series electric actuator is a kind of motor rotation force through multistage reduction gear, worm gear and other mechanisms, and finally through the output shaft,in the form of rotation 90° to switch the valve device, mainly drive and control the Angle travel valve opening, such as butterfly valve, ball valve, plug valve, etc.Valve-like applications. EOM integration type torque range is 35-20000N.m. EOM series conventional electric actuator no clutch operation, durable,the stroke is stable and reliable, effectively improving the transfer efficiency.
