Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pneumatically actuated for cleanroom use
Actuated versions for automatic control in fabs are not hand-operated.
If integral to semiconductor testing apparatus
Valves solely for Chapter 84 semiconductor processing machines classify with the machinery.
If butterfly type disc mechanism
Butterfly valves rotate a disc parallel to flow, distinct from rising gate perpendicular motion.

Import Tips & Compliance
• Provide cleanroom compatibility certs (e.g
• low particle emission) for semiconductor end-use
• Document as 'hand-operated' explicitly; many cleanroom valves are actuated
