Butterfly Valve Types and Technical Differences

Types of Butterfly Valves and Their Technical Differences are among the most preferred valve types for fluid control in industrial systems. These valves stand out due to their practical design and efficient operating principles. They are particularly effective in directing water, gas, and chemical substances. However, each butterfly valve has different characteristics, so technical details must be carefully considered when making a selection. So, what are the types of butterfly valves and their technical differences?

Manual Butterfly Valves and Their Application Areas

Manual butterfly valves are opened or closed by means of a hand-operated lever. They are generally preferred in low-pressure systems and operate effectively in irrigation lines and small-diameter piping installations. However, these valves may be insufficient in systems that require automation. To review the products developed with UNOX’s expert engineering, you may visit the UNOX website.

Advantages of Actuated Butterfly Valves

These valves, operated by electric or pneumatic actuators, provide remote control capability. This feature offers significant convenience, especially in automation systems. However, they cannot operate without an energy source. With their technical specifications, they deliver high efficiency across various industries.

Difference Between Metal-Bodied and Plastic-Bodied Valves

Metal-bodied butterfly valves are resistant to high pressure and offer long service life. However, these valves are more expensive compared to plastic models. Plastic-bodied valves, on the other hand, are cost-effective and lightweight, but their temperature resistance is limited. To determine the most suitable option for your application, you can receive expert support via the UNOX website.

Technical Details of Disc and Seat Materials

The performance of butterfly valves varies depending on the disc and seat materials. When the disc is manufactured from stainless steel, it provides resistance against chemicals; however, this may increase the overall cost. For the seat, different materials such as EPDM, NBR, and PTFE are used. Each material offers advantages under different temperature and pressure conditions. If you need support in material selection, the unoxonline website can assist you.

Differences Between Flanged and Lug Type Butterfly Valves

Flanged butterfly valves are installed between two flanges. This type of valve is used in locations where the system may need to be dismantled; however, the installation process takes longer. Lug type butterfly valves, on the other hand, are mounted using bolts, allowing maintenance to be performed without removing the valve from the piping system. This results in significant time savings. To compare the details of both models, you can review the information available on the unoxonline website.

Key Considerations When Selecting a Butterfly Valve

For proper valve selection, the operating pressure, temperature, and type of fluid must be taken into consideration. In addition, the valve body, disc material, and seat structure should be compatible with each other. However, not only technical specifications but also the intended application are important.
