A ductile iron double eccentric butterfly valve is a type of butterfly valve that is designed to handle a variety of fluids and gases in industrial applications. The valve is made of ductile iron, which is a type of cast iron that is known for its strength, durability, and corrosion resistance.
The double eccentric design of the butterfly valve means that the disc is offset from the centerline of the valve seat, which reduces the friction between the disc and the seat and allows for a tighter seal against leakage. This design also allows the valve to provide precise control over the flow of fluids and gases, making it suitable for use in a variety of industrial processes.
The ductile iron construction provides additional durability and corrosion resistance, making it suitable for use in harsh environments where other materials may deteriorate over time. The valve may also feature a resilient seat made of EPDM rubber or a similar material to provide a tight seal against leakage.
Wholesale ductile iron double eccentric butterfly valve are commonly used in a variety of industries, including oil and gas, chemical processing, and power generation. They can be operated manually using a handwheel or lever, or equipped with a motorized actuator for remote operation.
