Enertork

Enertork makes actuators, motorized devices that open and close the valves controlling the flow of liquids and gases in large industrial facilities, as well as the gear reducers used alongside them.

Its customers include power plants (hydroelectric, thermal, gas, combined-cycle, and nuclear), water and wastewater utilities, gas distributors, refineries, shipyards, and steelmakers, with the remainder being general industrial plants; products are supplied directly to end users or attached to valves through valve manufacturers. Listed on KOSDAQ, Korea's tech and small-cap board, the company competes in a narrow global field alongside a small number of established international rivals, where brand reputation and reliability carry more weight than price.
