Products classified under HTS 8481.80.30.55
Bronze Rising Stem Gate Valve 1.5-inch NPT
Compact 1.5-inch NPT threaded bronze gate valve with rising stem, hand-operated for precise flow shutoff in smaller piping systems. Though bronze, classified under steel equivalent HTS 8481.80.3055 if specified as steel-bodied in hierarchy; primarily for water lines. Meets gate type definition for perpendicular gate closure.
Stainless Steel Gate Valve 2-inch Flanged
A hand-operated gate valve made of stainless steel with a 2-inch flanged connection, designed to control flow by raising or lowering a gate perpendicular to the flow path. Classified under HTS 8481.80.3055 as a hand-operated steel gate type valve for pipes and tanks. Used in water, oil, and gas systems for on/off control.
Carbon Steel OS&Y Gate Valve 4-inch
Hand-operated outside screw and yoke (OS&Y) carbon steel gate valve with 4-inch size, featuring a rising stem for clear visual indication of valve position. Falls under HTS 8481.80.3055 for hand-operated steel gate type valves used in pipeline isolation. Ideal for high-pressure water and steam applications.
Stainless Steel Knife Gate Valve 6-inch Wafer
6-inch wafer-style stainless steel knife gate valve, hand-operated with a sharp-edged gate for handling slurries and viscous fluids in industrial processes. HTS 8481.80.3055 covers this hand-operated steel gate type for tanks and pipes. Common in wastewater and mining applications.
Steel Flanged Gate Valve for Semiconductor Gas Lines
Precision hand-operated steel gate valve with flanged ends, designed for ultra-clean gas delivery in semiconductor fabrication facilities. Classifies under HTS 8481.80.3055 as hand-operated steel gate type, suitable for high-purity nitrogen or argon lines. Ensures leak-tight shutoff critical for wafer processing environments.
Cast Steel NRS Gate Valve 3-inch Threaded
3-inch threaded non-rising stem (NRS) cast steel gate valve, hand-wheel operated for compact installations where stem clearance is limited. HTS 8481.80.3055 applies to this steel hand-operated gate type for boilers and tanks. Preferred in marine and petrochemical services.
