Triple Eccentric Butterfly Valve Design

What are triple eccentric butterfly valve design?

A triple eccentric butterfly valve design features a circular disc that rotates within the valve body to control the flow. In an eccentric disc butterfly valve, the disc rotates around an axis that is offset (eccentric) from the center of the valve body. Conversely, 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 types are used to regulate flow but have unique design characteristics.

The Features Between Eccentric And Concentric Butterfly Valves

As quality triple eccentric butterfly valve design from China butterfly valves supplier, triple eccentric butterfly valve design 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, triple eccentric butterfly valve design is isolation valves, then it allows pipe/vessel insulation for control/drainage. Secondly, if triple eccentric butterfly valve design is as control valves, it will be in piping manifolds to direct flow between multiple lines. Thirdly, when triple eccentric butterfly valve design 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.
