Abstract
A sleeve valve comprising a conduit, a gate, and a shut-off member. The conduit and the shut-off member are fixed in position relative to each other. The gate is movable relative to the shut-off member between opened and closed positions. The gate engages the shut-off member when the gate is in the closed position in a manner preventing fluid from flowing through the fluid passageway of the gate. The opened position of the gate allows fluid to flow through the valve. The valve is devoid of any structure within the fluid passageway of the gate attaching the shut-off member to the conduit.
