Products classified under HTS 8481.30.10.10
Copper Spring Check Valve 3/4 Inch
A 3/4-inch copper spring-loaded check valve for preventing reverse flow in hydronic heating systems and potable water pipes, using a spring to seat the poppet. Falls under HTS 8481.30.10.10 due to its copper construction and low-pressure rating under 850 kPa. Compact design suits tight spaces in HVAC and residential installations.
Brass Silent Check Valve 2 Inch
2-inch brass silent check valve with cushioned disc closure to reduce water hammer in larger low-pressure water mains. Fits HTS 8481.30.10.10 as copper alloy check valve under 850 kPa. Installed in municipal water distribution and fire protection systems.
Bronze Horizontal Check Valve 3/8 Inch
3/8-inch bronze horizontal inline check valve for fuel oil lines and low-pressure gas applications, oriented for horizontal piping. Under HTS 8481.30.10.10 for copper content and pressure spec. Prevents siphoning in heating oil systems.
Brass Swing Check Valve 1/2 Inch
A 1/2-inch brass swing check valve designed to prevent backflow in low-pressure plumbing systems, featuring a hinged disc that swings open with forward flow and closes against reverse flow. Classified under HTS 8481.30.10.10 as a copper check valve with pressure rating under 850 kPa, ideal for residential water lines and irrigation. Its copper alloy construction ensures corrosion resistance in non-industrial applications.
Bronze Lift Check Valve 1 Inch
A 1-inch bronze lift check valve where the disc lifts vertically in the flow direction and drops to seal against backflow, used in low-pressure air and water systems. HTS 8481.30.10.10 applies for its copper alloy (bronze) body and sub-850 kPa rating. Commonly installed in pump discharge lines for residential and light commercial use.
Brass Inline Check Valve 1/4 Inch
Compact 1/4-inch brass inline check valve for refrigerant lines and compressed air systems under low pressure, with ball or poppet mechanism. Classified in HTS 8481.30.10.10 for copper construction and pressure under 850 kPa. Essential for small appliance servicing and pneumatic tools.
Copper Y-Pattern Check Valve 1-1/4 Inch
1-1/4 inch copper Y-pattern check valve for angled flow in low-pressure steam and condensate return lines, minimizing pressure drop. HTS 8481.30.10.10 due to copper material and <850 kPa rating. Used in boiler feed systems and light industrial plumbing.
Copper Threaded Check Valve 1-1/2 Inch
1-1/2 inch copper threaded-end check valve for easy installation in low-pressure irrigation and washdown systems. HTS 8481.30.10.10 classification for copper check valves <850 kPa. Durable against corrosion in outdoor agricultural use.
