Description
- Manufacturer: Oliver Valves, a leading supplier of instrumentation and pipeline products.
- Function: A Double Block and Bleed (DBB) valve offers double isolation with a third bleed port, enabling safe maintenance and calibration of instrumentation by preventing leaks.
- Body Material: The ASTM A350 LF2 is a low-temperature forged carbon steel material, specified for use in cryogenic and other low-temperature applications.
- Design: These valves can be designed in various configurations, such as floating ball or trunnion mounted, to meet specific application requirements.
- ASTM A350 LF2 Properties: As a forged material, A350 LF2 offers superior strength and toughness due to its refined grain structure, ensuring greater fatigue resistance and consistency.
How it works:
- Primary Isolation: The first ball (obturator) closes to stop the process flow.
- Bleeding: The bleed valve opens to vent any trapped pressure between the two isolation balls.
- Secondary Isolation: The second ball closes, providing complete isolation for maintenance.
This combination of double isolation and bleeding functionality significantly enhances safety and efficiency in critical industrial processes.
