Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed solely for pressure reduction
Dedicated pressure-regulating valves have their own subheading outside transmission specifics.
If classified as valve parts rather than complete
Individual components like spools or solenoids go to parts provisions.
If primary function is automatic flow regulation
Highly automated control valves may classify as automatic regulators in Chapter 90.
