Chemoil Advance Technology supplies Dual Seal Plug Valves with Double Block and Bleed (DBB) configuration from recognized manufacturers for reliable isolation in pipeline and process applications. These valves are designed for applications where dependable isolation and the ability to separate sections of a process system are important.

The double block and bleed arrangement provides two independent sealing barriers with a bleed or venting provision between the sealing points, depending on the valve design. This configuration can help support safe isolation and verification of the isolated section during maintenance and process operations.
