Service Selection
Gate Valves for Hydrogen (H₂) Service
Which gate valves configuration suits Hydrogen (H₂) (H₂), in which material, to which standard — from real service data, with the pitfalls flagged.
Which gate valves for Hydrogen (H₂)?
Inconel 625 gate valve - High-pressure HP (700 bar) hydrogen - refuelling stations Typical service window: 0.1–700 bar (process to HP storage), -253°C (liquid H₂) to 550°C (reformer).

Governing Standards for Hydrogen (H₂) Service
ISO 15848 Class A (zero fugitive emissions)API 6D (pipeline valves)ASME B31.12 - Hydrogen piping and pipelinesEN 13648 (hydrogen cryogenic)ISO 11114-4 (HE of metals)
What to Avoid in Hydrogen (H₂) Service
- High-strength steel bodied valves (HRC > 22)
- NBR or EPDM seated valves - high permeation
- Non-fire-safe valves in any H₂ service
Service Considerations
- Fire-safe design mandatory - API 607 / ISO 10497
- Anti-static device mandatory - API 608
- All valves must be cleaned and degreased for H₂ service
- No dead-legs in valve design - H₂ accumulates in pockets
- For 700 bar H₂ fuel cell stations - SAE J2601 refuelling protocols
