Non-lubricate sealing

Plug valves feature two seats energized by a single obturator, with a drain port between them. Achieving bubble-tight sealing, the obturator (plug) forces the segments against the body seats. This sealing is independent of line pressure and can be verified online, making the plug valve a genuine API 6D Double Block & Bleed Valve.

In flammable fluid lines, pressure buildup inside the valve cavity can lead to accidents. To prevent this, Plug Valves come with an inbuilt cavity pressure relief system. Additionally, plug valve seats can be renewed without removing the valve from the pipeline. When in the open position, segments can be retracted from the seat and replaced after removing the bottom cover. Care should be taken to drain the line. For online verification of seat integrity and to drain the body cavity, Plug Valves are supplied with a drain port.
