DBB Valves Undergo Fugitive Emission Tests for UAE

One piece flange x flange double block and bleed valves are put through extended testing and ISO fugitive emission tests at the request of our customer in the United Arab Emirates.

Material and specification of these valves are; stainless steel, 20mm ball valves, 3” raised face (class 300), fitted with ½” vent and fire safe handle locking systems.

The first 24x DBB valves of a much larger order undergo fugitive emission and pressure testing pictured here on our new test rigs in Knutsford, England. Once they’ve successfully completed the rigorous process, they’ll leave for the Middle East.
