Product Description
What are three eccentric butterfly valve?
A three eccentric butterfly valve consists of a circular disc that rotates within the valve body to open or close flow. In an eccentric disc butterfly valve, the disc rotates around an axis that is offset (eccentric) from the center of the valve body. A concentric butterfly valve has a disc that rotates concentrically – meaning the axis of rotation aligns with the centerline of the valve body and pipe. Both are used to regulate flow but have distinct design features.
The Distinctive Traits of Eccentric and Concentric Butterfly Valves
As a reputable supplier of quality three eccentric butterfly valve from China, three eccentric butterfly valve takes pride in offering a range of butterfly valves that possess remarkable features. Today, we shall compare two types of butterfly valves – eccentric and concentric – and highlight the unique characteristics of each:
- Eccentric Disc Valves: These valves exhibit a more linear flow characteristic, ensuring a consistent velocity as they open or close. This results in reduced turbulence during operation, allowing for smoother flow control.
- Concentric Valves: In contrast, concentric valves possess a more progressive flow trait. As the valve opens, the flow rate increases non-linearly, leading to a higher degree of turbulence. This can be advantageous in certain applications where specific flow characteristics are desired.
- Installation Benefits: Eccentric valves offer installation advantages in compact spaces where concentric valves may not fit between pipe flanges. The offsetting of the disc allows for more flexibility in tight installations, ensuring efficient use of available space.
- Design Simplicity: On the other hand, concentric valves boast a simpler design, without the additional clearance required by the offset motion of an eccentric disc. This straightforward design can be advantageous in applications where simplicity and ease of maintenance are prioritized.
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, three eccentric butterfly valve is isolation valves, then it allows pipe/vessel insulation for control/drainage. Secondly, if three eccentric butterfly valve is as control valves, it will be in piping manifolds to direct flow between multiple lines. Thirdly, when three eccentric 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.
