1. A ball valve system, comprising:
a body having an upstream end and a downstream end;
a ball within the body between the upstream end and the downstream end, the ball being rotatable about a vertical axis to move between a closed position and an open position;
a stem movable so as to translate in an actuation direction substantially parallel to the vertical axis, the stem including a linearly-extending recess at a proximal portion of the stem; and
a guide pin extending within the recess of the stem, the guide pin and the recess being configured to prevent rotation of the stem when the stem moves in the actuation direction without rotating, to actuate the ball, the guide pin having a first end that has a first opening and a second end, opposite to the first end, that has a second opening, wherein the first and second openings form a channel through the guide pin and the second end is located within the recess of the stem so as to form a lubrication port to supply lubrication to the stem.
