Double Block and Bleed

ItalBest Valve manufactures a complete line of high quality double ball DBB (Double Block & Bleed valves). It is deemed the best choice in complying to safety measures thanks to the combination of two valves in one body and space saving with just two spheres . ItalBest Valve designs double ball DBB valves with adjustable flow pressure drain plugs in the middle.
Our double ball DBB valve can perform the tasks of 3 separate valves (2 isolated valves and 1 drain valve) which, apart from being extremely space saving, can also save on weight and time when it comes to installation and maintenance, requiring much less work and all 3 valves being located in one body. Double Block & Bleed Valves operate on the principle that isolation can be achieved from both the upstream and downstream process flow / pressures.
Our Double Block & Bleed valves are available in an extensive range of designs, materials, sizes and pressure classes and are in full conformance with ASME, API and NACE specifications. All Double Block & Bleed Valves are designed in accordance with ASME B16.34 directives and where applicable with API 6D or BS EN ISO 17292 directives. Different options for specific service conditions or client requirements are available, such as fully welded body or split body, etc.
