Product
Overview

The NOM series electric actuators are the most suitable for butterfly
valves, ball valves, and small sized valves.
They offer torque ranging from 35 Nm/310 inlb to 4,500 Nm/40,000 inlb.

A unique feature of this actuator is that the manual override can be operated without a clutch
and a brake.

All of the models are ISO 5211 compliant and are equipped with a continuous mechanicalbusiness as an assembly manufacturer.

position indicator and manual override (except NOM-B & NOM-A).

After more than half century, our products are widely used in industrial infrastructure, startingwith the precision gears inserted into various industrial machinery, to jack lifting devices usedin IT-related production facilities, liquid crystal panels and steel, and valve actuators used in
power plants and water and sewage, receiving high appraisal from domestic and global markets.
We aim to continue improving our special technology together with innovating our production
process, providing our customers with better service and products, and contributing to society
