This explosion barrier valve is extremely effective inflow areas with low dust concentration in the explosive category 1 and 2 range. They function without external electrical detection and control systems and their unique design allows them to be reconditioned, maintained and reused at exceptionally low cost of operation. The construction uses a valve poppet suspended in the flow area between one or two valve seats. When an explosion occurs, the poppet is thrown against the internal valve seat by the pressure wave moving ahead of the flame front. It then locks into a closed position.
