Flanged Concentric Butterfly Valve

What are flanged concentric butterfly valve?

A flanged concentric butterfly valve consists of a circular disc that pivots within the valve body to manage the flow. An eccentric disc butterfly valve features a disc that rotates around an axis offset (eccentric) from the valve body’s center. In contrast, a concentric butterfly valve has a disc that rotates concentrically, meaning the axis of rotation coincides with the centerline of the valve body and pipe. Both are utilized to regulate flow but possess unique design attributes.

The Enchanting Distinctions of Eccentric and Concentric Butterfly Valves

As a distinguished purveyor of exquisite flanged concentric butterfly valve from China, flanged concentric butterfly valve takes immense pride in presenting a splendid assortment of butterfly valves imbued with remarkable features. Today, let us delve into the intricate world of two captivating valve types – eccentric and concentric – and unravel the enchanting traits that set them apart:

• Eccentric Disc Valves: These valves exude a harmonious flow characteristic, akin to a melodious symphony. As they gracefully open or close, their movement maintains a linear flow pattern, ensuring consistent velocity. This serene dance of fluid control minimizes turbulence, creating a tranquil and seamless flow experience.
• Concentric Valves: In contrast, concentric valves possess a dynamic and progressive flow trait, reminiscent of a vibrant crescendo. As the valve opens, the flow rate increases in a non-linear fashion, infusing the system with a controlled turbulence. This captivating performance allows for applications where specific flow characteristics are desired, adding a touch of artistic brilliance to fluid dynamics.
• Installation Flexibility: Eccentric valves bestow upon us the gift of adaptability, especially in compact spaces where concentric valves may struggle to fit between pipe flanges. With their offset disc design, eccentric valves gracefully navigate confined installations, optimizing the utilization of available space.
• Design Simplicity: Yet, concentric valves radiate an aura of elegant simplicity, embracing a design without the additional clearance requirements of an eccentric disc’s offset motion. This streamlined design offers a seamless and hassle-free operation, delighting users with its effortless maintenance and functionality.

The Applications of Both Of Butterfly Valves Between Eccentric & Concentric

As quality butterfly valves for these two types, Both see wide chemical, oil/gas, power, marine and more. For instances, Firstly, flanged concentric butterfly valve is isolation valves, then it allows pipe/vessel insulation for control/drainage. Secondly, if flanged concentric butterfly valve is as control valves, it will be in piping manifolds to direct flow between multiple lines. Thirdly, when flanged concentric butterfly valve as shut-off valves in ductwork or wherever flow needs regulating in changing conditions.

Eccentric Disc Butterfly Valves:

• Throttling service: These valves are designed for precise flow control in applications where linearity is crucial, such as pumping stations, HVAC systems, and processing plants.
• Space-constrained installations: When pipe centerlines are too close together to accommodate a concentric valve, eccentric disc valves offer a practical solution due to their accommodating design.

Concentric Butterfly Valves:

• On/off applications: Concentric valves excel in applications where gradual filling or emptying is less critical, such as ballast tanks or surge tanks.
• Cost-effective solutions: With a simpler design that requires less precision and clearance, concentric valves offer a more economical option without compromising performance.
• Large water transmission mains: These valves are well-suited for large-scale water transmission mains, where the impact of turbulence is minimal due to the pipe diameter-to-flow ratio.
