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.

Consider a dovetail groove see attached links.
