Claim 21:
22. A hydraulic fracturing system, comprising:
a frac pump coupled via flow conduits to a wellhead tree capping a wellbore, the frac pump configured to deliver a fracturing slurry to the wellhead tree, wherein the frac pump includes one or more valve assemblies, each of the valve assemblies including:
a seat ring member;
a poppet, wherein a plug-side of the poppet is configured to fit in an opening of the seat ring member when the valve assembly is in a closed state and the plug-side is configured to be outside of the opening when the valve assembly is in an open state;
a valve post, wherein one section of the valve post extends through the plug-side and an opposite section of the valve post extends through a seat-side of the poppet; and

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 the valve post 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.
