Double Block & Bleed Valves
A Double Block & Bleed valve can perform the tasks of three separate valves. It would replace two separate isolations valves and one drain valve. This results in huge space savings and a sizeable weight reduction, which are positive benefits for FPSO’s and oil platforms. Double Block & Bleed valves can be supplied according to API6D and API6A.
Our double block & bleed valves are available as forged or cast valves featuring exotic material options with short delivery times.
