Concentric Butterfly Valve Supplier

What are Butterfly Valves: Eccentric and Concentric Types?

A butterfly valve, a leading product from China in the concentric butterfly valve supplier market, features a circular disc that rotates within the valve body to control flow. En una válvula de mariposa de disco excéntrico, the disc rotates around an axis that is offset from the center of the valve body. A diferencia de, Una válvula de mariposa concéntrica tiene un disco que gira concéntricamente., meaning the axis of rotation is aligned with the centerline of both the valve body and the pipe. Although both types are used to regulate flow, they possess distinct design characteristics.

The Features Between Eccentric and Concentric Butterfly Valves

As premium butterfly valves from China’s concentric butterfly valve supplier field, both eccentric and concentric butterfly valves feature the following characteristics:

• Eccentric disc valves have a linear flow characteristic, maintaining consistent velocity and reducing turbulence as they open and close.
• Concentric valves exhibit a progressive flow trait, with the flow rate increasing non-linearly upon valve opening, resulting in more turbulence.
• The offset disc in eccentric valves enables installation in confined spaces where concentric valves cannot be accommodated between pipe flanges.
• Por otro lado, concentric valves are more straightforward in design, not requiring the additional clearance for the offset motion of an eccentric disc.

The Applications of Both Eccentric and Concentric Butterfly Valves

As a leading concentric butterfly valve supplier manufacturer in China, we produce both eccentric and concentric butterfly valves that are extensively used in the chemical, petróleo/gas, fuerza, marine sectors, y más. Examples of their applications include:
Válvulas de aislamiento: Used to isolate pipes or vessels for control or drainage.
Control valves: Utilized in piping manifolds to direct flow between multiple lines.
Shut-off valves: Employed in ductwork or other areas where flow regulation is necessary under changing conditions.
Válvulas de mariposa de disco excéntrico:

• Ideal for throttling service where flow control linearity is crucial, such as in pumping stations, sistemas de climatización, and processing plants.
• Suitable for installation in tight spaces where pipe centrelines are too close together for a concentric valve to fit.

Válvulas de mariposa concéntricas:

• Best for on/off applications where gradual filling or emptying is less critical, such as in ballast tanks or surge tanks.
• Preferred where low cost is a priority due to their simpler design that requires less precision and clearance.
• Suitable for large water transmission mains where turbulence has minimal impact due to the large pipe diameter-to-flow ratio.
