1. A horizontal valve assembly comprising:
a valve body;
a valve guide; and
a valve stem,
wherein the valve guide comprises:
a valve guide body, wherein the valve guide body is substantially cylindrical and has a valve guide bore extending longitudinally therethrough along a valve guide bore central axis, and wherein, in an assembled configuration of the horizontal valve assembly, the valve stem passes at least partially through the valve guide bore and connects the valve body to the valve guide;
first and second lower wings, wherein each of the first and the second lower wings extends radially outward from the valve guide body to a lower wing outer surface at a distal end thereof, such that the lower wing outer surface is a first radial distance from the valve guide bore central axis;
an upper wing extending radially outward from the valve guide body to an upper wing outer surface at a distal end thereof, such that the upper wing outer surface is a second radial distance from the valve guide bore central axis,
wherein the first radial distance is greater than an interior radius of a housing bore of a housing in which the horizontal valve assembly is positioned for use, such that, when the horizontal valve assembly is initially positioned in the housing bore prior to use, the valve guide bore central axis is vertically higher than the central axis of the housing bore.
