Detail Information

Piping Double Block & Bleed (DBB) Ball Valves

Valve Description: Ball valve, soft seat, trunnion type, bolted bonnet, DBB, dual ball/twin ball, three pieces, forged carbon steel

Body Material: ASTM A105
Nominal Diameter: 8 Inch
Nominal Class: Class 600 LB
Design / Manufacture: API 6D
Face to Face: ASME B16.10
Test and Inspection: API 598
End connection: RF
Mode of Operation: Gear Operation

The DBB ball valve, designed to replace the complex form of multiple valve connections in pipeline, utilizes a twin-valve design. By combining two valves into one body, a twin-valve design reduces weight and potential leaks paths while meeting requirements for double block and bleed.
