Pilot-Operated Pressure Reducing Valve
A sophisticated pilot-operated valve system that uses a smaller pilot valve to control a main valve for precise high-flow pressure reduction in water distribution lines. Falls under HTS 8481.10.0090 as other pressure-reducing valves for pipes and tanks. Ideal for municipal and commercial applications requiring stable outlet pressure.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-pilot simpler design
Direct-acting regulators without pilot control classify as other valves.
If hand/bicycle pump mounted
Pressure regulators specifically for pumps shift to pump parts classification.
If imported as replacement parts
Valve parts rather than complete appliances go to 8481.90.

Import Tips & Compliance
• Provide engineering drawings showing pilot mechanism to justify classification
• Ensure ASME certification for high-pressure models
• Common issue: undervaluing as residential model under different stats

Brass Diaphragm Pressure Reducing Valve
A brass-constructed diaphragm-type valve designed to automatically reduce high inlet water pressure to a lower outlet pressure for residential plumbing systems. It falls under HTS 8481.10.0090 as a pressure-reducing valve not specified elsewhere in the subheading, used for pipes and tanks in non-industrial applications. The diaphragm mechanism responds to downstream pressure changes to maintain steady output.
