1. A valve guide for a fracturing pump valve assembly, the valve guide comprising:
a ring member having one or more blades, wherein:
the one or more blades project inward from an annular ring of the ring member, a first side of the one or more blades defining a central space of the ring member, the central space configured to partially surround and contain a cross-sectional portion of a valve post of the valve assembly therein and the first side extending parallel to a long axis length of the valve post, and
the first side of the one or more blades define one or more gaps there-between to allow a fracturing slurry to flow there-through and prevent the valve post from passing out of the central space.
