What Is a Flanged Butterfly Valve?
The flanged butterfly valve operates as a quarter-turn mechanism to handle or block fluid flow. The valve operates by means of a shaft-mounted rotating disc, which functions between open and closed states during rotation. The unique feature of flanged butterfly valves rests in their two flanged ends that exist on opposite sides of the valve body. The flanged parts on the valve equipment enable the formation of a secure connection between pipe flanges to prevent leaks.
The flanged butterfly valve stands out because it offers a compact design with lightweight components and operates effectively at different pressures and temperatures. These valves can serve multiple operating material types from fluids to gases and semi-solid materials.
Types of Flanged Butterfly Valves
The flanged butterfly valve exists in multiple designs which fulfill different requirements of industrial applications. There exist several standard varieties of designed butterfly valves which I will list next.
1. Double Flanged Butterfly Valve
A double flanged butterfly valve acquires additional durability through its dual flanged attachment which extends from the valve body at both ends. The two-flanged structure makes this valve dependable for forceful systems while enabling it to support pipe weight requirements. The double flanged valve finds its applications in water treatment plants as well as power generation facilities along with heavy industrial applications.
2. Single Flanged Butterfly Valve
Single-flanged butterfly valves are equipped with a flange placed on a single valve surface to decrease both its weight and price. The valve finds its main use in systems operating at low pressure or situations which demand compact designs. The cost-effective choice among pipe installation projects is the single flanged valve design.
3. Concentric Flanged Butterfly Valve
This valve type arranges both the disc and the shaft to run through the middle of the valve body. Engineering this design reduces damage to components so it stands out as a preferred solution for systems needing exact flow management. The concentric valve design serves as a preferred solution for HVAC systems as well as chemical processing and food and beverage applications.
Materials – Why Ductile Iron Is the Preferred Choice
A flanged butterfly valve’s material selection directly affects its operational reliability and working performance. Ductile iron, as an industrial application material, remains the preferred choice among available choices.
Benefits of Ductile Iron:
Ductile iron stands out because of its high tensile strength which enables its use in lasting under demanding pressure conditions.
The protective epoxy coatings and alternative protective layers provide ductile iron valves with resistance to corrosive substances.
Manufacturers find ductile iron more cost-effective compared to stainless steel, along with other premium materials, despite offering equivalent quality standards.
RUFSUPPLY provides ductile iron-flanged butterfly valves that will deliver exceptional service duration and reliable performance for industrial applications.
Dimensions and Sizing Guide
When selecting valve sizes for optimal performance, one should pay attention since it determines the effectiveness against pressure drops and flow restrictions. The following table shows standard valve size measurements:
Smaller systems operating at moderate flow levels can use the 4-inch Flanged Butterfly Valve because of its compact dimensions.
The medium-sized system requires the 6-inch Flanged Butterfly Valve as a versatile solution to handle capacity needs while saving space needs.
Special orders enable customers to get large-sized or non-standard valves that fulfill their unique project requirements.
The flanged butterfly valve catalogue provides detailed specifications and technical drawings along with dimensions and material information and pressure ratings for all models.
Double Flanged Butterfly Valve vs. Lug-Type Butterfly Valve
The selection of butterfly valves entails an assessment between double flanged butterfly valves and lug-type butterfly valves according to potential buyers. The global function of both butterfly valve styles remains the same yet each one presents distinctive characteristics.
Double Flanged Butterfly Valve:
Strength: Offers superior stability, especially in high-pressure systems.
This valve type provides the best performance in vital operational settings that need to bear the weight of the pipeline.
Bolting operations happen on both sides of the valve which results in increased security but requires additional time for setup.
Lug-Type Butterfly Valve:
This valve finds placement on pipeline terminal points or operates between two joined flanges.
The price of these valves is generally lower than that of double-flanged models.
The valve works effectively for systems that maintain reduced pressure levels while requiring a less heavy valve construction.
Analysis of valve-specific features will assist you in selecting a suitable valve for your particular application.

To install a flanged butterfly valve:
- Check whether the valve size and pressure rating provided by the supplier match the pipeline used.
- Ensure that the disc of the valve is correctly situated by ensuring the assembly of the valve is aligned with the flange.
- You should, however, be stretched equally around the valve body and tightened in a number of cross-clutch to avoid putting pressure on the valve body.
- You should check if the seal is set correctly and the system works fine after Installation of the software.
It is, therefore, evident that different materials apply to the manufacture of flanged butterfly valves in relation to the intended use:
This type of metal is highly recommendable for companies operating in areas with corroding conditions such as chemical industries or marine use.
Ductile Iron: This pipe material used for most general industrial application due to the qualities such as being both strong and cheap.
PTFE-Lined Valves: Best for handling aggressive chemicals or high-purity applications.
Aluminum Bronze: Suitable for seawater and other harsh environments.
Leakage: The most usual problem that can be related with high pressure is leakage, which can be caused by worn seals, or bolts that were not tightened properly. Replace damaged gaskets if necessary.
Very stiff Operation: Check the condition of the valve stem for any sign of dirt or corrosion, and always ensure that any moving part is lubricated.
Diameter: Make sure the closed diameter of the disc is according to its declared specifications and no obstacles are hindering the flow within the pipe.
Misalignment: Correct the alignment of the valve in order to overcome operation problems.
Therefore, flanged butterfly valves are commonly used where there are high chances of corrosion, and this is in the following industries:
- Industrial units are used in the treatment of chemical fluids that contain acids and alkali substances.
- Marine systems for seawater applications.
- Food and beverage industries for hygienic fluid control.
- The treatment plants to manage the water both treated and untreated water.
It should be a habit always to check the valve and determine if it is wearing out or not.
Clean the valve components in order to minimize on the accumulation of sediments or other debris.
Apply oil or grease the stem and other parts of the instrument such as cones and cones so that friction is minimized.
It is recommended to replace seals and gaskets as frequently as possible thus enhancing their efficiency in providing a tight seal.
Some of the forces that can affect the performance of the valve include pressure and temperature of the systems that the valve is working on, and therefore in order to enhance its value the pressure and temperature should not be allowed to exceed the valve’s upper limit.
Flanged Butterfly Valve: It’s a valve that is well-suited for systems which require full-face flange connections and hence provide high-pressure conditions.
Lugged Butterfly Valve: This valve has a protruding bolt providing a flange connection. Thus, it is designed to shut down one-half of the pipeline for ease of maintenance.
The choice depends on the pressure that is expected to be exerted on the system and whether a certain segment requires isolation for a repair work to be carried out.
Yes,indeed flanged butterfly valves are ideal for high pressure ones and above the rating of ANSI 150. They are made of high quality and they are suitable to be used in areas where the introduction of pressure can is very necessary such as in oil and gas, power generating companies and even water treatment plants.
