1. CF8 Disc: CF8 is cast grade 304 stainless steel, has excellent corrosion resistance and is widely used in various applications, including corrosive fluids.
2. Valve body: the material is aluminum, which is much lighter than other metals like ductile iron, wcb. the most important is that aluminum naturally forms a protective oxide layer when exposed to air, which helps resist corrosion.
3. Replaceable soft seat: When the valve seat is worn, there is no need to replace the entire valve, just replace the valve seat, soft back seat is easier to replace than hard back seat.
4. Stainless steel 420 Stem: it offers good corrosion resistance, high strength, and hardness.
5. This Disc of butterfly valve is one piece type without pin, this prevents the medium from corroding the valve plate and valve stem through the pin hole.
6. Butterfly Valve Testing Standard: ISO 5208, API598, EN1266-1.
7. Butterfly Valves Applications: Butterfly Valve Is Used For Water system, waste water system, and gas pipelines with temperatures ≤120°C and nominal pressures ≤16MPa in food, medicine, chemical industry, petroleum, electric power, urban construction, textile, papermaking, etc.
