SBB & DBB Ball Valve
The Double Block and Bleed (DBB) Ball Valve is designed to minimize leakage, simplify installation, and reduce pipeline pressure. By replacing multiple interconnected valves, it saves space, lowers costs, and facilitates maintenance. Featuring two sealing slides on the plug, it provides double blocking and bleeding functionality, making it ideal for isolating media in pipelines carrying aviation fuel, natural gas, liquefied gas, and chemicals.
The Single Block and Bleed (SBB) Ball Valve is a versatile valve that integrates the functions of a block valve and a bleed valve into a single unit. It is designed to isolate sections of a pipeline for maintenance or repair while providing a reliable means to release trapped pressure or fluid downstream. Unlike double block and bleed valves, the SBB valve features a simpler design with two key components: a block valve, typically a ball, gate, or globe valve for isolation, and a bleed valve, usually a needle or globe valve, for pressure release.
