Check valves for hydrogen applications
FK-Series check valve
This Swagelok® check valve is specifically designed for hydrogen filling station applications. It allows one-way flow and provides a highly reliable shut-off for low molecular weight gases. The valve prevents backflow when the differential pressure falls below the opening pressure.
Note: Not for use as a safety relief valve.
Key product features:
ISO 19880-3 process (100 000 cycles).
Pressure rating: 1050 bar (15 229 psig ) .
Temperature range: -40°C-85°C (-40°F-185°F).
High flow coefficient: up to 4.5 Cv.
Body material construction: 316 SS with >12% Ni
Why are high quality components essential for hydrogen applications?
The future of hydrogen as a fuel depends on the safety and long-term durability of the systems. Given the low molecular weight of hydrogen, all valves and components must be particularly leak-proof, reliable and durable. The use of the right materials and technologies, such as stainless steels and seals resistant to hydrogen fracture, is key.
Characteristics and requirements for hydrogen valves:
Valves used in hydrogen systems must meet a number of requirements to ensure safety, durability and functionality. These requirements include:
- Tight joints and durable construction: valves must be made of high quality materials that can withstand high pressures and repeated use.
- Design features that improve safety: For example, solutions that prevent parts from becoming loose or damaged during use.
- Pressure resistance: Valves must be compatible with the requirements of hydrogen systems, such as withstanding pressures of 350-700 bar.
- Resistance to temperature and pressure fluctuations: Valve seals and other components must perform reliably under varying conditions.
- Hydrogen embrittlement prevention: The materials used must be of high quality and designed to withstand the stresses of hydrogen, such as embrittlement.
- Compatibility with other system components: Valves shall be compatible with hydrogen components without leakage risks or material problems.
By considering these characteristics in their entirety, you can contribute to a safer hydrogen system. The long-term success of hydrogen technology depends on carefully selected components.
