Abstract: A dual shut-off valve including a valve body defining an interior cavity and a flow tube passing therethrough, an outer cylinder including a body portion defining an interior cavity and a through hole passing therethrough, the outer cylinder being rotatably disposed within the interior cavity of the valve body, and an inner cylinder including a body portion defining a through hole passing therethrough, the inner cylinder being rotatably disposed within the interior cavity of the outer cylinder, wherein the inner cylinder and the outer cylinder are both rotatable between a first position in which the through holes of the outer cylinder and the inner cylinder are aligned with the flow tube and a second position in which the through holes of the outer cylinder and the inner cylinder are transverse to the flow tube.
