Abstract
A gate valve includes a valve body and a valve cover. The valve body includes 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 has a central longitudinal axis and a ridge defining a perimeter of the third opening. The valve cover can fit over the third opening and, under force on the valve cover, exert a clamping force on the ridge. The clamping force has a first force component perpendicular to the central longitudinal axis and a second force component parallel with the central longitudinal axis. The first force component of the clamping force is toward the gate channel. The ridge includes a first surface configured to mate with a first surface of the valve cover.
