DuraSeal double block and bleed plug valves are cited in this free 14-page brochure to deliver "bubbletight, fire-safety sealing integrity and the ability to double block and bleed from a single valve."
Designed for applications that require frequent gas or liquids isolation and testing, models are cited for product manifolds, measurement units, processing equipment isolation, or loading racks and tank isolation. Nine specific applications are summarized.
With diagrams and illustrations, the literature highlights how the plug designs seal mechanically. They are easily automated using hydraulic, pneumatic, or electric actuators. A detailed set of illustrations depict how DuraSeal works.
Three ANSI 150, 300, 600 series are specified with tabular data and schematics to come in a range of 2 to 24, 2 to 14, and 2 to 12-in. sizes respectively. DuraSeal valve is by design a bidirectional DIB-1 valve.
