content: The gate of the valve is a conical plug that swings on an arm from a pivot above it. When closed the gate fits a conical seat in the valve body; when opened it swings up into the top of the valve body practically clear of the passages. The peculiar feature of the valve is the arrangement of parts, which permits the closing of a swing-gate valve by means of a hand wheel and screw.
