Rotork actuators supplied to Korean fuel cell PP

Rotork linear actuators have been selected to control the flow of hydrogen gas at a fuel cell power plant in South Korea.

More than 90 CVL linear electric actuators and 184 ExMax quarter-turn electric actuators are to be installed on US fuel cell technology company Doosan Fuel Cell’s project at a Hanhwa Total Co. Ltd plant in Daesan.

The actuators will operate globe and ball valves which control the flow of hydrogen gas in fuel cells at the site. Each fuel cell will include two CVL actuators and four ExMax actuators.

A fuel cell is a generator which creates electricity and heat through the electrochemical reaction of hydrogen and oxygen. It has no transmission or distribution costs meaning it can reduce energy costs by more than 25%.

The CVL includes an explosion-proof feature which was key in the customer specifying the Rotork product while the ExMax includes a fast spring return function which will also improve the failsafe efficiency and accuracy of the operation.

Rotork’s CVL actuators use a 1-phase or DC power supply to provide highly accurate and responsive continuous modulation of control valves without the complexity and cost of a pneumatic supply.
