Choosing the right butterfly valve body material is critical for performance and service life. This article explains the strengths and limitations of the most common materials — including cast iron (FC), ductile iron (FCD, GGG40, GGG50, DI), carbon steel (WCB, A105), stainless steel (CF8/CF8M), duplex stainless steel (2520, 2507), aluminum bronze, and plastics (PVC, CPVC, PVDF). We cover where each material fits best: from water and HVAC pipelines to chemical, marine, and high-temperature applications. A quick selection guide with corrosion resistance ratings helps buyers make faster, smarter decisions.
