Key Features & Operating Applications |
| Double Offset (High Performance) |
Shaft offset from seat plane and pipe centerline; minimizes seat wear; ideal for hydrocarbons and steam. |
| Triple Offset (Zero Friction) |
Third offset cone angle eliminates camming friction entirely; delivers true metal-to-metal bubble-tight sealing. |
| Cryogenic Triple Offset Valves |
Extended bonnet column isolating gland packing from cryogenic LNG and liquid oxygen media. |
| Steam Isolation High Performance |
Replaces bulky gate valves on steam headers; lighter weight and lower maintenance. |
