1. A gate valve comprising:
a valve body including a first opening, a second opening, a third opening, a flow passage from the first opening to the second opening, and a gate channel from the flow passage to the third opening, the gate channel having a central longitudinal axis and a ridge defining a perimeter of the third opening; and
a valve cover configured to fit over the third opening and, as a result of force parallel to the central longitudinal axis on the valve cover toward the valve body, to exert a clamping force on the ridge, the clamping force having a first force component perpendicular to and toward the central longitudinal axis and a second force component parallel with the central longitudinal axis,
the ridge including a first surface configured to mate with a first surface of the valve cover, a second surface configured to mate with a second surface of the valve cover, and a slot extending between the first surface of the ridge and the second surface of the ridge.
