Gate valve with angled body

A gate valve comprising:

• a valve body having a gate cavity formed by opposing walls extending to a first end of the valve body;
• a through bore intersecting the gate cavity and the opposing walls;
• seat pockets formed in the opposing walls around the through bore;
• the opposing walls extending parallel to each other from the seat pockets to a first kickoff point and the opposing walls diverge from each other and oblique to the center axis, from the kickoff point to the first end whereby the opposing walls form a sloped first gate cavity opening between the first kickoff point and the first end;
• a gate positioned in the gate cavity and moveable between a closed position blocking flow through the through bore and an open position allowing flow through the through bore, the gate having a sealing face extending perpendicular to the through bore;
• a three-dimensional frame of reference with three mutually orthogonal directions, wherein an X-axis corresponds to a center axis of the through bore, a Y-axis corresponds to a center axis of the gate cavity, a Z-axis is generally centered through a side of the gate wherein a Y-Z plane is parallel to the sealing face;
• a first bonnet coupled to the first end and forming a first terminal gate cavity end having a diameter substantially equivalent to a diameter of the sloped first gate cavity opening at the first end;
• and
• a lubrication port having an opening in the first terminal gate cavity end and a channel through the first bonnet, wherein the channel and the lubrication port opening are oblique to a Y-Z plane and oriented toward the sloped first cavity opening.
