MRE – TYPE

MRE – TYPE

Electric Actuator, Quarter Turn

Used for controlling 0°~270° rotation of the valves and similar products, such as butterfly valves, ball valves, dampers, flapper valves, cock valves, etc.
It drives by 380V/220V/110V AC Power. Control signal is 4-20mA current signal or 0-10Vdc voltage signal, enables move the valve to the desired position, achieving its automation, maximum output torque is up to 4000 Nm.

Widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, building auto-control, light industry and other industries.
