Swagelok has revealed two new components engineered for safe and efficient operation in hydrogen refuelling stations.
The Swagelok ramp regulator provides controlled pressure during refuelling, while the Swagelok FK series hydrogen check valve delivers unidirectional flow and shut-off of small-molecule gases, preventing reverse flow.
Hydrogen must be stored at pressures in excess of 700 bar, and the rapid thermal and pressure changes at refuelling stations can impact system integrity.
The Swagelok ramp regulator serves applications in accordance with SAE J2601— the worldwide standard for hydrogen refuelling stations — and features a maximum allowable working pressure of 1050 bar inlet and 875 bar outlet.
Its operating temperature range is –40° to 85°C, and it can reach a 120 g/s hydrogen tank fill rate. An optional PID control unit will communicate with the dispenser to reach the required pressure control profile.
The Swagelok FK series hydrogen check valve also features a maximum allowable working pressure of 1050 bar and handles a temperature range of –40° to 185°F (–40° to 85°C).
With a high flow coefficient, all-metal body seal, and a spring that’s isolated from the flow path to increase its service life, it has passed third-party hydrogen testing per ISO-19880-3 and effectively prevents reverse flow when the differential drops below the fixed cracking pressure of < 2 bar.
Swagelok’s FK technology can be installed up to five times faster than cone and thread fittings, reducing installation time, assembly, and maintenance costs.
