Double Block & Bleed and Double Isolation

The VE® 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. 

The VE® Dual Expanding Plug Valve provides several different bleed systems and a pressure relief device according to the requirements of API 6D. Custom solutions can also be produced on request.
