Classification: 116/277

location of a valve closure that can be adjusted with respect to the associated seat of the valve, e.g., in a closed, open, or intermediate position.
(1) Note. When the valve is broadly recited, e.g., when there is an insufficient number of parts thereof to make a complete working valve, these patents are proper for Class 116; when a complete working valve is claimed, e.g., including a valve closure plus a valve seat or passage, etc., these patents are in Class 251.
