In an electromagnetic force motor operated valve for controlling the flow of fluid, the improvement comprising: a valve member having a head portion defining a sealing surface and a bearing surface converging in a direction away from said sealing surface and towards an axis disposed to essentially centrally intersect with said sealing surface, and a shank portion arranged in alignment with said axis and projecting from said bearing surface in a direction away from said sealing surface; a valve seat adapted to receive said sealing surface in fluid sealing relationship therewith; a mounting member for mounting said valve member and being operably connected to said force motor for moving said valve member to position said sealing surface in and out of said sealing relationship, said mounting member having an opening facing towards said valve seat and sized to loosely receive said shank portion and an annular bearing edge portion bounding said opening relatively adjacent said valve seat, said bearing edge portion defining a seat for supporting said bearing surface to permit said valve member to undergo rotatable/tilting movement relative to said mounting member and to assume an adjusted position relative thereto, during initial assembly of said valve, as required to permit seating of said sealing surface in said sealing relationship with said valve seat incident to movement of said valve member towards said valve seat by said mounting member; and retaining means operable after said initial assembly for thereafter retaining said valve member in said adjusted position relative to said mounting member.
