Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If equipped with proportional solenoid actuation
Proportional hydraulic valves have separate statistical suffix for precise flow modulation via electronic control.
If for general industrial use outside pneumatic/oleohydraulic transmissions
Other appliances may classify under general valves if not specifically for fluid power transmissions.
If imported as replacement parts without system specification
Valve parts or unspecified components fall under parts provisions rather than complete valves.
