Modular double block and bleed valves combine two in-line isolation valves into a single body with an additional bleed valve used to drain or vent trapped fluid between the two obturators to ensure highest level of safety in double isolation and bleed service. Using a double block and bleed valve versus two separate valves saves weight and space on the piping layout and ensures a significant reduction of potential leakage to the atmosphere, minimizing any hazardous risk when transferring liquids or gas. Several unique features are available to offer advanced technical solutions suitable to deal with aggressive and severe offshore environments. Material selection is fully customizable to meet customers project specifications.
