Claim 7:
8. A valve assembly, comprising:
an actuator configured to drive movement of a valve stem between a first position and a second position;
a valve body, having a chamber for a valve member coupled to the valve stem, wherein movement of the valve stem drives movement of the valve member between the first position and the second position, the movement of the valve stem is along a vertical axis of the valve body, the first position permits flow through a passage extending along a horizontal axis of the valve body, and the second position blocks flow through the passage;
a fluid end adapted to couple to the valve body, the fluid end having a plurality of fluid end lugs, extending radially outward from a horizontal axis and arranged circumferentially about the fluid end, the plurality of fluid end lugs separated by respective gaps of a plurality of gaps, the fluid end being translatable along the horizontal axis between a coupled position and a decoupled position, wherein the plurality of fluid end lugs axially move through a plurality of valve body slots as the fluid end transitions from the decoupled position to the coupled position, and the fluid end is rotatably placed into the coupled position after moving through the plurality of valve body slots;
an environmental seal positioned between the fluid end and the valve body at an outer radial diameter of the fluid end between the valve body and the fluid end at an interface between the valve body and the fluid end, the environmental seal arranged within a groove formed in the fluid end and positioned external to the plurality of fluid end lugs and the plurality of valve body slots along the horizontal axis such that the plurality of fluid end lugs are closer to the vertical axis than the environmental seal; and
a valve seat arranged within a recessed portion formed in the fluid end, the valve seat being removable from the valve body through a common opening, and the fluid end being removable from the valve body through the common opening when the actuator is coupled to the valve body, wherein the valve seat is positioned to engage the valve member as the valve member moves axially to the second position, and the valve seat extends away from the plurality of fluid end lugs along the horizontal axis, to a location that is closer to the valve member than the plurality of fluid end lugs.
