Double Block and Bleed Valves

Double Block and Bleed Valves (DBB)

Our product range covers standard double block and bleed valves (DBB), where body, ball, stem, seat and blled valve materials can be customized with nickel alloys and other special materials.

Double Isolation and Bleed Valves (DIB)

Double Isolation and Bleed valves (DIB) differ from Double Block and Bleed valves as they offer a seal from both sides at the same time, plus the option of an additional seal from one side only.

Why use our DBB and DIB valves?

Both offer space-saving solutions and are, in principle, ball, gate or expanding plug valves modified to offer a reliable seal. DBBs and DIB also reduce piping, weight and the overall envelope compared to using a multiple-valve solution.
