Double Block and Bleed (DBB) ball valves are critical components in industrial fluid control systems, designed to provide reliable isolation and safety by ensuring that no fluid can pass through the valve when it is closed. The sealing integrity of DBB ball valves is essential for preventing leaks,

Basic Principles and Structure of DBB Ball ValvesThe core function of a DBB (Double Block and Bleed) ball valve is to control the on-off of fluid through the rotation of the valve ball. Its structural design includes a ball fixed inside the valve body, with a through hole on the ball. When the throu

Understanding DBB Ball ValvesDBB ball valves are designed to provide two independent seals (double block) and a bleed function to vent trapped pressure between the seals. This design ensures that the valve can safely isolate sections of the pipeline, preventing cross-contamination and facilitating m

Understanding Double Block and Bleed (DBB) Ball ValvesDBB ball valves are designed to provide two independent blockages and a bleed path to ensure complete isolation and venting of the fluid. This design is particularly useful in applications where maintenance or repairs are required, as it allows f
