The body of a gear-operated butterfly valve is typically made from ductile iron GGG40 or carbon steel ASTM A216, providing adequate strength for pressures of 10 to 16 bar. The valve disc is commonly manufactured from stainless steel 304 or 316, offering high mechanical durability along with excellent corrosion and wear resistance. The internal lining and seat are often composed of EPDM, NBR, or polyurethane coatings to ensure tight sealing and long service life when exposed to various fluids. This combination of materials delivers stable performance, low operating torque, and suitability for water, wastewater, oil, and chemical pipelines.
