Double Block & Bleed Plug Valve

A Double Block & Bleed (DBB) Plug Valve is an industrial valve designed to isolate a section of a pipeline or system while providing a means to vent or bleed the cavity between two isolation barriers. This design enhances safety and simplifies maintenance procedures by ensuring that the isolated section is fully de-pressurized and can be safely serviced or inspected. The DBB feature helps to prevent the escape of gas or fluid, improving overall system reliability and safety.
