Flanged butterfly valves are widely used in industrial piping systems where a strong connection and reliable shut-off are required. With flanged ends on both sides of the valve body, they bolt directly between two pipe flanges, creating a secure seal that can withstand higher pressure and larger pipe diameters compared to wafer or lug styles. This makes the flanged butterfly valve a trusted choice for industries that need dependable performance in demanding operating conditions.
A flanged butterfly valve uses a rotating disc mounted on a shaft to regulate or stop the flow of liquid or gas. When the handle or actuator turns the disc parallel to the flow, the valve opens fully. Rotating the disc to a perpendicular position closes the valve, providing tight shut-off. The flanged ends distribute stress evenly across the pipeline connection, helping maintain durability and reducing the risk of leakage under pressure.
Flanged end butterfly valves are well-suited for applications where high strength and accessibility are important. They are commonly used in:
Water treatment plants and distribution networks
Power generation and HVAC systems
Oil and gas processing pipelines
Chemical and marine industries handling corrosive or abrasive media
In each case, the ability to isolate sections of the pipeline and the straightforward installation process make flanged type butterfly valves a practical solution.
Flanged butterfly valves are manufactured in a variety of materials to match different operating environments. Stainless steel flanged butterfly valves provide superior resistance to rust and chemical attack, making them suitable for aggressive fluids or marine settings. Cast iron and carbon steel options are often selected for general water supply or moderate-pressure systems, where cost control is important but performance cannot be compromised.
The double flange butterfly valve design offers added stability for larger diameter pipelines, reducing vibration and supporting long-term performance under continuous operation.
These valves are available in a wide range of sizes to meet industrial standards, making them adaptable to small, medium or large-scale projects. From compact lines to high-capacity pipelines, flanged butterfly valves provide the reliability required by plant operators, engineers and contractors.

What makes flanged butterfly valves suitable for high-pressure or large-diameter pipelines?
The flanged ends provide a rigid, bolted connection that distributes stress evenly, making the valve stable and reliable under higher pressure and larger line sizes.
Where are flanged butterfly valves most commonly used?
They are widely used in water treatment, power plants, HVAC systems, oil and gas pipelines, chemical processing and marine operations.
How does a flanged butterfly valve control flow?
A rotating disc inside the valve opens or closes the passage. Turning the disc parallel allows full flow; turning it perpendicular stops the flow.
What materials are typically available for flanged butterfly valves?
Common materials include stainless steel, carbon steel and cast iron, selected based on pressure, temperature and fluid compatibility.
When should a double-flange butterfly valve be used?
Double-flange designs are preferred for larger diameters or systems requiring added stability to reduce vibration and maintain consistent sealing.
Are flanged butterfly valves easy to install or replace?
Yes, the bolted flange connection allows straightforward alignment and removal when system maintenance is required.

I bought the wrong fittings and then ordered the correct ones. I have reached out multiple times and I see about how to return the wrong fittings and have gotten no response. I’m happy with what I got I’m just not happy you’re not responding and sticking me with the incorrect ones
