Dual Expanding Plug Valve
| 13
The dual expanding plug valve has been developed to substitute the principle of two in-line valves with
a drain and or bleed valve, as further described and shown in the previous page. The special design of
the sealing mechanismminimizes wear, securing a long lasting safe and reliable flow control solution.
Four different versions

Dual Expanding Plug Valve exists in different executions:
• Figure no. 2300 Reduced Bore – Standard Version
• Figure no. 2301 Full Bore Piggable
• Figure no. 2302 Full Bore Pig-launcher
• Figure no. 2304 Four-Way Diverter Valve
Double Block & Bleed and Double Isolation (according to API-6D/ISO14313)

Dual Expanding Plug Valve provides two seating surfaces, each of which, seal to both directions. When the valve is in closed
position, each individual seal is fully isolating not allowing any leakage, either from downstream or upstream or from the body cavity. In
case of body cavity overpressure, venting/bleeding is provided by a thermal relief. Therefore the downstream pipeline is fully isolated from
upstream pressure without the need for pressure balancing.

Dual Expanding Plug Valve provides several different bleed systems and a pressure relief device according to the requirements of
API 6D. Page 20 and 21 show an overview and description of all the different options. Custom solutions can also be produced on request.
