RE: oring main seal on b-fly valve

This valve has an o-ring in a groove running around the perimeter of the valve disc?  It will probably always pop out under high differential pressure.  Butterfly valves built for high delta-p have a seal (tadpole or several other styles) that is held in place in the housing.
