What is A DBB Ball Valve?
A DBB ball valve, or Double Block and Bleed ball valve, is a type of valve that provides two separate sealing barriers, or blocks, to isolate fluid flow in a pipeline. It also includes a third valve, known as a bleed valve, for safely relieving pressure or draining trapped fluids between the blocks. The DBB ball valve offers enhanced safety and efficiency by eliminating the need for multiple valves and reducing the potential for leakage in critical applications.
DBB ball valves find applications in industries where safety and reliability are paramount, such as oil and gas, chemical processing, and refining. They offer a compact and efficient solution by combining multiple functions into a single valve, reducing the need for additional valves and potential leak points.
Enhanced Safety
The double block and bleed design of the valve offers enhanced safety compared to traditional single-block valves. It provides an extra layer of protection by creating two independent barriers against leakage, reducing the risk of fluid escape and potential hazards in critical systems.


Space and Cost Efficiency
DBB ball valves offer space and cost efficiency by combining multiple functions into a single valve body. With the inclusion of the double block and bleed features, there is no need for additional valves or complex piping arrangements, resulting in reduced installation costs and a smaller footprint.
