Claim 0:
1. A valve assembly, comprising:
an actuator adapted to drive movement of a valve member axially along a vertical axis between an open position and a closed position;
a bonnet coupled to the actuator;
a valve body coupled to the bonnet;
a fluid end coupled to the valve body;
a quick connection system adapted to couple the fluid end to the valve body, the quick connection system comprising:
a plurality of valve body lugs separated by a plurality of spaces, the plurality of valve body lugs extending radially outward from an axis;
a plurality of fluid end lugs configured to interact with the plurality of valve body lugs, the plurality of valve body lugs being arranged to axially align with the plurality of fluid end lugs to block axial movement of the fluid end with respect to the valve body; and
an environmental seal positioned within a recess formed in the fluid end, the environmental seal arranged external to the plurality of valve body lugs and the plurality of fluid end lugs, wherein the environmental seal is positioned at a first position, the plurality of valve lugs are positioned at a second position, and the plurality of valve body lugs are positioned at a third position, along a horizontal axis of the fluid end, such that a first distance between the first position and the valve member is greater than a second distance between the second position and the valve member and a third distance between the third position and the valve member, wherein the environmental seal is positioned at an interface between the valve body and the fluid end at an outer diameter of the fluid end; and

a valve seat arranged within a recessed portion formed in the fluid end, the fluid end being removable from the valve body through a common opening, and the valve seat being removable from the valve body through the common opening when the bonnet 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 closed position, and the valve seat extends away from the quick connection system along the horizontal axis, perpendicular to the vertical axis, to a location that is closer to the valve member than the plurality of valve body lugs and the plurality of fluid end lugs.
