8481.80.30.15 - Globe type

This HTS category, 8481.80.30.15, specifically classifies globe type valves and similar appliances. These valves are characterized by a mechanism that operates by a disc or plug moving up and down to control the flow of fluid within a larger, often spherical or globe-shaped body. They are typically used in piping systems, boiler shells, tanks, vats, and similar applications where precise flow control, throttling, or shut-off is required. This subcategory falls under hand-operated iron valves, emphasizing their manual operation and primary construction material.

Distinguishing this category from its siblings is crucial for accurate classification. Unlike the gate type (8481.80.30.10), which uses a sliding gate, or the ball type (8481.80.30.25), which employs a rotating ball, globe valves utilize a movable disc that seats against a stationary ring within the valve body. The plug type (8481.80.30.20) typically involves a tapered or cylindrical plug for flow regulation, and the butterfly type (8481.80.30.30) uses a disc that rotates on a central spindle. This category, "Globe type," is distinct due to its specific internal mechanism designed for throttling and precise flow modulation.

As this is a leaf node within the HTS classification system, there are no further subcategories to introduce. Therefore, the focus remains on clearly defining the characteristics of globe type valves and ensuring they are accurately distinguished from other types of valves at the same level of detail within the broader "Other appliances: Hand operated: Of iron or steel: Of iron" grouping. The classification hinges on the physical design and operational principle of the valve's closure member.
