Check Valves for Oxygen (O₂ - Industrial and Medical Grade) Service
Which check valves configuration suits Oxygen (O₂ - Industrial and Medical Grade) (O₂), in which material, to which standard — from real service data, with the pitfalls flagged.
Which check valves for Oxygen (O₂ - Industrial and Medical Grade)?
Check Valve (SS 316, spring-loaded piston) - LOX / GOX pump discharge - non-return to prevent oxygen backflow into compressor. Typical service window: Near-atmospheric (LOX storage) to 300 bar (high-pressure GOX cylinders / distribution), −183°C (liquid oxygen) to 60°C (GOX distribution).

Governing Standards for Oxygen (O₂ - Industrial and Medical Grade) Service
What to Avoid in Oxygen (O₂ - Industrial and Medical Grade) Service
- Any valve containing hydrocarbon lubricants - ignition risk in pure oxygen
- Carbon steel valves above 10 bar pure oxygen - burns in high-pressure oxygen
- Elastomeric seats or seals not oxygen-compatible (natural rubber, NBR, standard EPDM)
Service Considerations
- Oxygen service cleaning: all wetted surfaces must be degreased and cleaned per ASTM G93 / CGA G-4.1 before installation - hydrocarbons ignite in oxygen
- Maximum flow velocity: GOX in stainless steel valves limited to 15–30 m/s - adiabatic compression ignition risk above this
- No copper alloy valves containing iron - iron oxide particles in GOX can ignite
- LOX: all cryogenic precautions plus oxygen-specific material and cleanliness requirements
- Dead legs and manual sample connections must be avoided - oxygen-enriched areas create extreme fire/explosion hazard
