Valves for LPG - Liquefied Petroleum Gas Service
LPG (propane/butane mixture) is stored and transported as a pressurised liquid. Pressure vessels and pipelines typically operate at 5–20 bar. Valves must be API 6D or equivalent, fire-safe, and antistatic. LPG is odourless in pure form - ethyl mercaptan is added as an odorant.
Pressure Range
5–25 bar liquid; 1–5 bar vapour distribution
Temperature
-42°C (propane) to ambient
Industries
LPG bottling plants, Petrochemicals, Domestic & commercial cooking
What valves are used for LPG - Liquefied Petroleum Gas service?
API 6D ball valve (CS) are recommended for LPG - Liquefied Petroleum Gas service: LPG storage, bottling, and pipeline service - fire-safe required.
Key Properties - LPG - Liquefied Petroleum Gas
- Stored as liquid under pressure - vaporises on pressure release
- Propane boiling point: -42°C | Butane boiling point: -1°C
- Highly flammable - LEL 1.8%, UEL 9.5% (propane)
- Heavier than air - accumulates in low-lying areas and drains
- Standard carbon steel is acceptable for liquid and vapour phase

Material Compatibility - LPG - Liquefied Petroleum Gas
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/A105/A333 Gr.6) | Excellent | Standard material for LPG at all temperatures. |
| SS 316L | Excellent | Acceptable - often used for instrument and small bore fittings. |
| Ductile Iron | Good | Low-pressure LPG distribution systems. |
| Brass/Bronze | Fair | Acceptable for low-pressure domestic fittings. Not for industrial HP service. |
| NBR (Nitrile) | Good | Good for LPG seals and seats at ambient temperature. |
| PTFE | Excellent | Preferred for seats and seals. |
