What is Double Block and Bleed Valves? Why use a Double Block and Bleed valve? Double Block and Bleed valves have evolved to replace the process of bolting together individual valves to provide dual isolation. This new assembly provides great savings in weight, space and installation times especially in instrument or instrument cage isolation. However the greatest savings are to be seen in the reduction of leak paths to atmosphere, therefore reducing the risk of the potential hazards this entails. Dual isolation is a necessary requirement when maintenance is taking place down stream of the first isolation valve.
