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.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 of the operation.
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.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 of the operation.
Rotork’s CVL actuators use a 1-phase or DC power supply to provide continuous modulation of control valves.The CVL ensures flow control with resolution figures better than 0.1% and repeatable positional control using a 4-20 mA signal. It features a thrust range of 890 N to 22,241 N (200 to 5,000 lbf). With an on-board data logger included as standard, the CVL is Bluetooth compatible for local setup, control and diagnostics.
Rotork’s ExMax actuator uses a 24-240 VAC/VDC power supply and provides a torque range of 5 to 150 Nm (3.7 to 110.6 lbf.ft) and can operate in temperatures ranging from -40 to +50 °C (-40 to +122 °F). It also provides ingress protection to IP68 standards and is ATEX explosionproof certified.
