What Are the Differences Between Flanged Butterfly Valves and Wafer Butterfly Valves?

Flanged butterfly valves and wafer butterfly valves are commonly used types of valves in fluid control systems. They have significant differences in terms of design, functionality, and application.

Below, we will discuss in detail the main differences between these two types of butterfly valves. Let's take a look!

1. Structural Characteristics

(01) The defining feature of a flanged butterfly valve is that it has flanges on both ends of the valve. These flanges allow the valve to be securely connected to the pipeline flanges using bolts. This design enhances the valve's sealing performance, ensuring stable operation in various working environments. Companies like YEKE Valve offer a range of high-quality flanged butterfly valves that ensure reliable performance even under harsh conditions. For more details, you can visit YEKEVALVE.COM.

(02) In contrast, the wafer butterfly valve is directly installed between two pipeline flanges using double-ended bolts. This design gives the wafer valve a more compact structure, saving space, especially in situations where pipe placement is limited. Wafer-style butterfly valves are particularly advantageous in tight spaces and complex installations.

2. Operation Method

(01) Wafer butterfly valves are often operated using electric actuators, which provide a high degree of automation and ease of operation. The valve can be controlled remotely, improving work efficiency and reducing the cost of manual operation. YEKE Valve’s wafer butterfly valves, with their electric actuator options, provide reliable and cost-effective solutions for automated systems.

(02) Flanged butterfly valves, on the other hand, are typically operated manually or pneumatically. While this method is relatively simple, it lacks the high level of automation offered by electric wafer butterfly valves.

3. Performance and Sealing Ability

(01) Flanged butterfly valves, thanks to their unique flange connection design, maintain excellent sealing performance even under high pressure, high temperature, or corrosive media environments. This makes them ideal for heavy-duty applications.

(02) Although the wafer butterfly valve has a simpler structure, its wide flange sealing surface design is capable of meeting the requirements for a variety of HVAC fluid media. This design effectively meets all flange connection standards, and installation does not require additional gaskets, making it easier to use in many settings.

4. Applications

(01) Flanged butterfly valves, due to their outstanding sealing performance and stable operational features, are widely used in systems for water treatment plants, power plants, steel mills, paper mills, chemical industries, and other sectors that require water supply and drainage equipment.

(02) Wafer butterfly valves are more suitable for situations that require frequent operation and higher levels of automation. They are commonly found in commercial buildings, public buildings, and municipal water systems or ventilation systems.

Conclusion

In summary, flanged butterfly valves and wafer butterfly valves each have their unique features and areas of application. When choosing a valve, it is essential to consider the specific working environment and requirements to ensure the selected valve meets the system's operational needs. Additionally, regardless of the type of butterfly valve chosen, regular maintenance and inspection are necessary to ensure long-term, stable operation.
