Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If stainless steel construction
Stainless variants use steel subcategory even if similar design.
If for high-pressure safety shutoff applications
Safety or relief valves have dedicated classification regardless of butterfly design.
If imported as unfinished castings
Unmachined iron castings are classified by material and state, not function.
