1. A valve seat assembly for a reciprocating pump, the valve seat assembly being insertable into a bore in a fluid end casing of the reciprocating pump, the valve seat assembly comprising:
a strike ring having a first body, the first body having a first end surface, a second end surface opposite the first end surface, and a first outer surface, the first body having a first inner surface that defines a first bore extending through the first body, the second end surface being a most upstream portion of the first body with respect to a pumping chamber in the fluid end casing; and
a support sleeve having a second body, the second body having a third end surface, a fourth end surface opposite the third end surface, and a second outer surface, the second outer surface having a different configuration than the first outer surface, and the third end surface of the second body being engaged by the second end surface of the first body, the second body defining a second inner surface that defines a second bore extending through the second body, the third end surface being a most downstream portion of the second body with respect to the pumping chamber in the fluid end casing, wherein the strike ring is engageable by a valve, the first body and the second body are separable from engagement with each other, the first bore is aligned with the second bore when the first body is proximate to the second body.
