Modular Double Block & Bleed (DBB) valves are engineered and manufactured to provide a compact and reliable alternative to multiple instrument valve systems, reducing leak paths and saving installations and maintenance costs. Double Block and bleed valves are a space-saving double insulation that reduces the need for costly multi-valve systems. By combining all
blocking and purging components in a single unit, JC DBB flanged or threaded ball valves
minimize the risk of leakage pathways to the atmosphere while providing significant weight
