Rotork actuators control gas flow at Korean fuel cell power plant

Hundreds of Rotork’s electric actuators will be used to control the flow of hydrogen gas at a fuel cell power plant located in South Korea.

Over 90 CVL linear electric actuators, as well as 184 EnMax quarter-turn electric actuators will be installed on Doosan Fuel Cell’s project at Hanhwa Total’s fuel cell plant in Daesan, South Korea. The actuators will be used to operate globe and ball valves, which control the flow of hydrogen gas in fuel cells.

Each fuel cell will include two CVL actuators and four ExMax actuators, acting as a generator to create electricity and heat through the electrochemical reaction of hydrogen and oxygen. The fuel cells have no transmission or distribution costs so can reduce energy costs by over 25%. They are also able to operate 365 days a year.

The CVL actuators include an explosion-proof feature, while the EnMax products feature a fast spring return function, which will improve failsafe efficiency and accuracy.
