This feature can be provided in one direction or in both directions. the difference between api’s dbb and dib definitions is that a double block and bleed valve seals against pressures from both sides of the valve while a double isolation and bleed valve provides an additional seal against pressure from only one side. The difference between api’s dbb and dib, then, is that a double block and bleed valve seals against pressures from both sides of the valve, while a double isolation and bleed valve provides an additional seal against pressure from only one side. for applications that require an additional pressure barrier that seals separately from the main. There is an important distinction between dbb and dib as they often fall under the same category and are used interchangeably within the industry. dib valves can isolate either side of the valve regardless of the presence of upstream or downstream pressures. and often, dib valves are referred to as “double block and bleed valves.”.

There is an important distinction between dbb and dib as they often fall under the same category and are used interchangeably within the industry. dib valves can isolate either side of the valve regardless of the presence of upstream or downstream pressures. and often, dib valves are referred to as “double block and bleed valves.”. In api’s dbb and dib definitions the difference is that a double block and bleed valve seals against pressures from both sides of the valve while a double isolation and bleed valve provides an additional seal against pressure building in the valve’s cavity. two configurations are available for dib ball valves — dib 1 and dib 2. First, the two valves under discussion: dbb – double block and bleed valve. dib – double isolation and bleed valve. in the most basic terms, the difference between a dbb and dib valve comes from the type of function the valve seat gives. with a ball valve seat there are two functions here to consider. the api (american petroleum institute.
