| Type | Common Materials | Applications | Key Features |
|---|---|---|---|
| One-piece ball valve | SS304 / SS316 | Water treatment, low-pressure | Low cost, compact structure |
| Two-piece ball valve | SS304 / SS316 | HVAC, chemical systems | Easy to maintain, better sealing |
| Three-piece ball valve | SS316 / CF8M | Pharma, food, petrochemical | Removable design, easy cleaning & repair |
| Flanged ball valve | SS316 / 316L | Oil, gas, high-pressure pipelines | Robust connection, suited for high-pressure use |
| High-platform ball valve | SS304 / CF8M | Automation systems | ISO 5211 mount, actuator-ready |
| Cryogenic ball valve | ASTM A351 CF8C / CF3M | LNG, liquefied gases | Withstands -196°C, extended bonnet |
| Fire-safe ball valve | SS316 / SS321 | Oil refineries, flammable gases | API 607 fireproof standard, anti-static design |
| 3-way/4-way ball valve | SS304 / SS316 | Media switching, mixing | Multi-port control, compact system layout |
SS316, 316L, CF8M: Preferred for high-corrosion and cold climate resistance (Siberia, Far East, Arctic regions).
SS304: Common in HVAC, water supply, food processing.
Flanged connections: Preferred for medium-to-high pressure systems due to sealing reliability.
Three-piece over one-piece: Better for frequent maintenance, cleaning, and modular use.
Growing demand for pneumatic and electric actuated ball valves in automated gas and chemical systems.
| Sector | Key Requirements | Typical Valve Types |
|---|---|---|
| Oil & Gas | Fire-safe, anti-static, high pressure | Flanged, fire-safe, high-platform valves |
| LNG / Cryogenics | Extreme low temperature, tight shutoff | Cryogenic ball valves with extended bonnet |
| Chemical plants | Corrosion resistance, ease of maintenance | Three-piece, high-platform valves |
| Food & Pharma | Sanitary design, easy cleaning | Three-piece, polished stainless steel |
| District Heating / HVAC | Budget-friendly, reliable | Two-piece, threaded ball valves |
