ECCENTRIC PLUG VALVE
Flow Designated


A browser capable of displaying graphics is required to view this information.

  As the plug component is rotated to valve closure, the offset condition of the plug causes the seating surface to move axially downstream into the nickel. The results in a high seating force thereby crushing trapped solids and resulting in a bubble-tight seal. The upstream pressure acting on the convex side of the plug furthur improves the bubble-tight seal.
   
  Upon opening the valve, the intial rotation of the plug causes the resilient seating surface to move axially away from the nickel seat in the body. This action minimizes wear and scraping of the resilient seat, thereby improving the life of the valve. The plug can be positioned at any position between open and closed for throttling applications.
   
  In the full-open position, the plug is rotated out of the main fluid stream as shown. This allows for high capacity flow through the valve.
