What Is a Double Block and Bleed Valve?
A double block and bleed ball valve consists of two isolation ball valves and one bleed valve in a single valve assembly. It is efficient in weight and space. Because of this, it promotes less work during installation and maintenance. This allows the operator to find and control all three valves in a single location.
Its main function is to simultaneously isolate upstream and downstream lines while bleeding the body to maintain stable isolation. Because of its verified zero leakage, it is suitable for crucial services, such as toxic fluid operations and high-pressure systems.
