3 Inch Flanged Butterfly Valve

3 inch flanged butterfly valve(DN80), Butterfly valves with standard flange interfaces at both ends are securely connected to pipeline flanges through bolts, ensuring good sealing. They are suitable for industrial piping systems that require frequent opening and closing or flow regulation.

The main components of the 3-inch flanked butterfly valve are made of different materials to ensure stable performance and long-term durability

Cast iron, ductile iron, carbon steel, stainless steel.

Usually stainless steel (304/316) or ductile iron coated with epoxy coating.

EPDM: resistant to water, steam, and weak acidity and alkalinity, suitable for hot water systems and water treatment.

NBR (Nitrile Rubber): Good oil resistance, commonly used in oil or mineral media.

PTFE (polytetrafluoroethylene): resistant to high temperature and strong corrosion, suitable for high demand working conditions such as chemical and pharmaceutical industries.

The 3-inch flanged butterfly valve, with its stable flange connection and reliable sealing performance, is widely used in the following scenarios:

Used for cutting off and regulating water flow in the inlet and outlet pipelines of water plants and sewage treatment plants.

Used for controlling media such as air, water, oil, steam, etc. in industries such as petroleum, chemical, papermaking, and power.
