Electric Three Eccentric Butterfly Valve

What are electric three eccentric butterfly valve?

A electric three eccentric butterfly valve comprises a circular disc that revolves within the valve body to either open or close the flow. In an eccentric disc butterfly valve, the disc rotates about an axis that is offset (eccentric) from the valve body’s center. On the other hand, a concentric butterfly valve has a disc that rotates concentrically, with the axis of rotation aligned with the centerline of the valve body and pipe. Both types are employed for flow regulation but exhibit distinct design features.

The Features Between Eccentric And Concentric Butterfly Valves

As quality electric three eccentric butterfly valve from China butterfly valves supplier, electric three eccentric butterfly valve gets many features. However, we will compare two types of butterfly valves and list each features below:

• Eccentric disc valves have a more linear flow characteristic, maintaining consistent velocity as they open/close. This causes less turbulence.
• Concentric valves have a more progressive flow trait where flow rate increases non-linearly with valve opening. This results in more turbulence.
• By offsetting the disc, eccentric valves allowInstallation benefits in compact spaces where concentric valves can’t fit between pipe flanges.
• However, concentric valves are simpler in design without the extra clearance required by an eccentric disc’s offset motion.

The Versatility of Butterfly Valves: Eccentric and Concentric

As quality butterfly valves for these two types, Both see wide chemical, oil/gas, power, marine and more. For instances, Firstly, electric three eccentric butterfly valve is isolation valves, then it allows pipe/vessel insulation for control/drainage. Secondly, if electric three eccentric butterfly valve is as control valves, it will be in piping manifolds to direct flow between multiple lines. Thirdly, when electric 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 specifically designed for applications that require precise flow control, particularly in situations where linearity is crucial. They are commonly used in pumping stations, HVAC systems, and processing plants.
• Space constraints: When the distance between pipe centerlines is too close to accommodate a concentric valve, eccentric disc valves come into play. Their design allows for installation in tight spaces without compromising functionality.

Concentric Butterfly Valves:

• On/off applications: Concentric valves are ideal for situations where gradual filling or emptying is less critical, such as ballast tanks or surge tanks. They provide reliable on/off functionality, ensuring efficient operation.
• Cost-effective solutions: With a simpler concentric design that requires less precision and clearance, these valves offer a more affordable option without compromising performance. They are often chosen when low cost is a priority.
• Large water transmission mains: Concentric valves are well-suited for use in large water transmission mains, where the impact of turbulence is minimal due to the favorable pipe diameter-to-flow ratio. They ensure smooth and efficient flow control in these demanding applications.
