Configuration Tool

Haskel offers specialized needle valves designed to handle high-pressure hydrogen in both gas and liquid forms, with ratings typically up to 20,000 PSI (1,378 bar). These valves are engineered to resist hydrogen embrittlement and provide leak-free performance in critical applications like refueling stations and fuel cell testing.

Key Specifications for Hydrogen Needle Valves
  • Pressure Ratings: Standard hydrogen-rated needle valves handle up to 20,000 PSI (1,378 bar).
  • Temperature Range:
    • Standard: -58°F to +392°F (-50°C to +200°C).
    • Extreme/Cryogenic: With an extended stuffing box, operation is possible down to -423°F (-253°C).
  • Materials: Constructed primarily of 316 cold-worked stainless steel to ensure longevity and safety.
  • Stem Options: Available with a treated 316 Stem (Suffix -H2-S) or High Nickel alloy (Suffix -H2-N) for superior resistance to hydrogen-induced cracking.
