Electro-Pneumatic Proportional Pressure Regulator
> This electro-pneumatic proportional pressure regulator converts an electrical control signal into a proportional pneumatic pressure output. It continuously measures the downstream pressure and adjusts the internal valve to maintain the desired setpoint, making it an automatic regulating instrument. Because its final control element operates pneumatically, it is classified as a pneumatic instrument under tariff item 9032.81.00.

More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the device is a simple manually adjusted valve without automatic feedback
Valves without automatic control are classified in heading 84.81.
If the final control element is purely electrical rather than pneumatic
Other automatic regulating instruments not hydraulic or pneumatic fall under 9032.89.
