Valve assembly

A valve assembly, comprising a housing defining a conduit through which a fluid may flow and a butterfly plate rotatably mounted within said housing so as to control the flow of fluid through said housing;

• said plate incorporating oppositely located projections which extend beyond the conduit;
• said plate and projections being of one piece and wherein each of said projections extends beyond said conduit into a respective one of two end recesses located in oppositely facing rotatable shafts so that the plate rotates within the housing together with said rotatable shafts;
• characterised in that the projections are held in place within said recesses, solely by the interfit between the valve components once the valve is assembled for use (e.g. with no screw or other auxiliary clamping means securing the projections to the shafts).

A valve assembly, comprising a housing defining a conduit through which a fluid may flow;

• and a butterfly plate rotatably mounted to said housing so as to control the flow of fluid through said housing;
• said plate incorporating oppositely located projections which extend beyond the conduit;
• characterised in that the housing is formed of at least two separable components so that when said at least two separable components arc separated the plate may be removed from said housing.

A valve assembly, comprising a housing defining a conduit through which a fluid may flow and a butterfly plate rotatably mounted within said housing so as to control the flow of fluid through said housing;

• said plate incorporating oppositely located projections each of which extends beyond the conduit and engages at a mounting location within the housing, so that the plate rotates within the housing;
• characterised by a slot extending from a said mounting location, along an inner housing surface defining the conduit to an outer housing surface, the said slot allowing a corresponding said projection to be inserted into its mounting location during assembly.
