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.

Choosing the right butterfly valve can be challenging — from water supply to chemical processing, each application requires a different solution. This buyer’s guide explains the main butterfly valve classifications: by function (water, sanitary 304L/316L, high-performance, corrosion-resistant, high-temperature, vacuum), by structure (concentric, double eccentric, triple eccentric), by connection (wafer, lug, flanged), and by operation (manual, electric, pneumatic). With over 30 years of valve manufacturing experience, we help buyers select the most reliable valve for their systems.
