Pneumatic Flow Control Valve for Air Systems
An automatic pneumatic flow controller that regulates air flow rates in pneumatic systems by sensing and adjusting to maintain set parameters against disturbances. Classified in HTS 9032.81.00.80 for other pneumatic automatic regulating apparatus, distinct from electrical or simple valves. Meets criteria for automatic control of pneumatic variables as per chapter definitions.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If non-automatic control valves for pneumatic circuits
Pneumatic valves without automatic measuring and regulating functions are under heading 8481 for general valves.
If for measuring instruments without regulating capability
Pure pneumatic flow meters without control functions classify in 9031 for other measuring optical/non-optical instruments.
If parts of specific pneumatic pumps or compressors
If principally for named pneumatic apparatus in 8412, classifies there per section XVI notes applied to chapter 90.

Import Tips & Compliance
• Confirm automatic feedback loop with sensors for flow/level; manual valves go to 8481
• Include pressure rating, material certs (e.g
• for corrosive environments), and system compatibility in import docs
