Integral double block and bleed valve

Integral double block and bleed valve is that a valve owns two balls. It could be opened and closed together or separately. The valve could be replaced with the multiple valves in traditional pipelines. Meanwhile, it reduce leakage point in pipeline system, with fast discharge and shutdown function. DBB ball valves can save installation space and reduce pressure of pipeline system. It also owns simplify installation procedure and reduces the cost of maintenance. At present, DBB ball valves made by ANIEC have been used by some end users such as Petronas.
