A pump fluid end comprising:
- a reciprocating element disposed at least partially within a horizontal reciprocating element bore of the pump fluid end having a central horizontal axis;
- a discharge valve assembly;
- and a suction valve assembly,
- wherein the suction valve assembly is a horizontal valve assembly comprising a valve guide, a valve body, and a valve stem connecting the valve body to the valve guide, wherein the horizontal valve assembly has a center of gravity outside the valve body and wherein the suction valve assembly is coaxial with the central horizontal axis of the horizontal reciprocating element bore.

A method comprising:
- removing a first horizontal guided valve assembly from a pump fluid end having a horizontal reciprocating element bore having a central horizontal axis, wherein the first valve assembly comprises a valve guide and a valve body and wherein the first valve assembly has a center of gravity proximate the valve body;
- and
- installing a second horizontal guided valve assembly in the pump fluid end, wherein the second valve assembly comprises a valve guide, a valve body, and a valve stem connecting the valve body to the valve guide and has a center of gravity that is moved a distance along a horizontal central axis of the second valve assembly in comparison to the center of gravity of the first valve assembly, and
- wherein the second horizontal guided valve assembly is coaxial with the central horizontal axis of the horizontal reciprocating element bore.
