Valves for Propane (C₃H₈ - LPG Component) Service
Propane is a liquefied petroleum gas (LPG) component used for domestic and industrial heating, as an industrial fuel, as a petrochemical feedstock (propane dehydrogenation to propylene), and as an aerosol propellant. At ambient temperature, propane exists as a liquid under moderate pressure (approximately 8.5 barg at 20°C). It is handled in bulk storage spheres, tankers, and pipelines in the oil and gas, petrochemical, and LPG distribution industries. Key valve requirements: fire-safe design, full-bore isolation, ESD capability, and NFPA 58/OISD-116 compliance.
Pressure Range
8–25 barg (ambient storage to pipeline operating pressure)
Temperature
−42°C (cryogenic storage) to +60°C (ambient max)
Industries
LPG storage and distribution, Domestic and industrial heating, Propylene production (PDH)
What valves are used for Propane (C₃H₈ - LPG Component) service?
Trunnion Ball Valve (WCB, fire-safe, ESD) are recommended for Propane (C₃H₈ - LPG Component) service: Storage sphere connection valves and pipeline ESD - fire-safe API 607, actuated for emergency shutdown.
Key Properties - Propane (C₃H₈ - LPG Component)
- Vapour pressure: ~8.5 barg at 20°C - liquefied under moderate pressure
- Boiling point: −42.1°C at atmospheric pressure
- Flash point: −104°C - extremely flammable, ATEX Zone 1 in all storage and handling areas
- Non-corrosive to carbon steel, SS, and most metals
- Compatible with PTFE and Viton seals; NBR also acceptable for propane

Material Compatibility - Propane (C₃H₈ - LPG Component)
Ratings are indicative. Actual compatibility depends on concentration, temperature, velocity, and presence of contaminants. Always consult corrosion tables or a materials engineer.
| Material | Rating | Notes |
|---|---|---|
| Carbon Steel (WCB) | Excellent | Standard for propane storage spheres and pipeline service. |
| A350 LF2 | Good | Required for cryogenic propane below −29°C. |
| SS 316L | Excellent | Optional - better corrosion resistance for propane with moisture. |
| PTFE seals | Excellent | Best for propane. |
| Viton (FKM) seals | Good | Good chemical resistance to propane. |
| NBR seals | Good | Acceptable for propane service at moderate temperature. |
