Abstract
A valve guide includes a valve guide body having a valve guide bore along a central axis thereof. In an assembled configuration of a horizontal valve assembly comprising the valve guide, a valve stem passes through the valve guide bore, connecting a valve body to the valve guide. The valve guide further includes first and second skis that each extends radially outward from the valve guide body to a lower wing outer surface, such that the lower wing outer surface is a first radial distance from the valve guide bore central axis; and an upper wing extending radially outward from the valve guide body to an upper wing outer surface. The upper wing outer surface is a second radial distance from the valve guide bore central axis. The first radial distance is greater than an interior radius of a housing bore the horizontal valve assembly is positioned in for use.
