Hydrogen valves Hydrogen, an energy carrier with a future.

Hydrogen ball valves are essential for the storage, transportation, and distribution of hydrogen. These valves regulate hydrogen flow in pipelines, storage tanks, and fuel cell systems, ensuring safe and efficient operation across various hydrogen applications.

Material & Temperature Resistance

Designed with materials that resist hydrogen’s corrosive effects, these valves perform reliably across a wide range of service temperatures, from liquid hydrogen to 500°C.

Seal Selection

• Material Hardness: Harder seals offer superior resistance to extrusion and are ideal for high-pressure systems. Softer seals are suited for irregular surfaces or low-pressure applications.
• Hydrogen Compatibility: Seals must be certified for hydrogen use to avoid embrittlement or cracking.
• Fire Resistance: Given hydrogen’s wide flammability range and colorless flame, the valves are designed to be inherently firesafe.
• Fugitive Emissions: Specially designed to minimize fugitive emissions, helping to address hydrogen’s potent impact as an indirect greenhouse gas.

Seal Design & Installation

Proper seal groove design ensures reliable performance. Correct installation prevents twisting or rolling, and lubricants or sealants may be required for optimal sealing.

Testing & Safety

Testing hydrogen ball valves typically involves the use of non-hydrogen gases (air, nitrogen, or helium) to ensure safety and prevent material degradation. However, hydrogen gas may be used for seal compatibility tests, always following strict safety protocols.

Hydrogen’s Unique Properties

• Leakage Prevention: Hydrogen’s small molecular size makes effective sealing crucial to prevent leaks.
• Hydrogen Embrittlement: Valves are crafted with materials resistant to hydrogen embrittlement, ensuring long-lasting durability under pressure.
