The 3 inch butterfly valve (DN80) is engineered for precise and efficient flow control in a wide range of industrial and commercial applications. This wafer type butterfly valve features a compact, lightweight design that allows for easy installation between flanges, making it ideal for pipelines with limited space.
Constructed with a ductile iron (DI) body, the valve offers superior mechanical strength and resistance to external pressure. The CF8 stainless steel disc ensures excellent corrosion resistance and extended service life, even in challenging environments. The NBR (nitrile rubber) seat provides a secure, leak-proof seal, offering chemical and oil resistance that makes it suitable for water, air, and low-pressure industrial systems.
This butterfly valve wafer type supports bi-directional flow and offers low torque operation for smooth handling. It is commonly used in HVAC systems, water treatment, and general pipeline projects. Whether you’re searching for a wafer style butterfly valve, a high performance butterfly valve, or a DN80 butterfly valve, this 3-inch model delivers reliable, long-term performance at a competitive price.
