Introduction to DBB Plug Valve
DBB (Double Block and Bleed) plug valves are specialized valves designed to isolate the upstream and downstream sections of a piping system effectively. They offer two separate sealing functions, along with a bleeding option to vent the cavity between the two seals. This design provides enhanced safety and reliability, especially in applications where preventing cross – contamination and ensuring tight shut – off are critical. DBB plug valves are widely used in industries such as oil and gas, chemical processing, power generation, and water treatment. DBB Plug Valve
