Butterfly valves are one of the most popular valves used in industrial applications. They are known for their simplicity and reliability and can be used in various industries. This blog post will discuss the advantages of using actuated butterfly valves in the industry.

Introduction


Actuated butterfly valves have many advantages over other types used in industry. They are easy to install and require little maintenance, which makes them ideal for use in industries where there is a need for frequent or automated operation of valves. In addition, they are less likely to leak than other valves and can be used with various fluids, including corrosive or abrasive ones.

What are Butterfly Valves?


Butterfly valves are quarter-turn valves used to control the flow of liquids and gases. They are named after their butterfly-shaped disc, which rotates to open or close the valve. Due to their reliability, durability, and cost-effectiveness, butterfly valves are widely used in industries such as food and beverage, pharmaceuticals, water treatment, and petrochemicals.

The Advantages of Butterfly Valves


Butterfly valves offer several advantages over other valves, making them ideal for many industrial applications.

One of the main advantages of butterfly valves is their compact design. Butterfly valves are much smaller and lighter than other valves, such as ball valves, making them easier to install and operate. This also makes them more cost-effective, requiring fewer installation materials and labor.

Butterfly valves also have a lower pressure drop than other types of valves. This is because the disc in a butterfly valve is always parallel to the flow of liquid or gas, regardless of whether the valve is open or closed. This reduces friction and allows for a smoother flow of liquids and gasses.

Butterfly valves are also less likely to leak than other types of valves. This is because the seal in a butterfly valve is located between the body and the disc rather than between the body and the seat (as in most other types of valves). This means there is less opportunity for the seal to be damaged or broken and, therefore, less chance of leakage.

Finally, butterfly valves are easy to maintain and repair. Because they have fewer moving parts than other valves, they are less likely to experience wear and tear. And if something goes wrong with a butterfly valve, it is usually easy and inexpensive to fix.

Types of Butterfly Valves


There are three main types of butterfly valves: wafer, lug, and double-offset. Wafer butterfly valves have a disc connected to the stem with two or more bolts. The bolts hold the disc in place, allowing it to rotate and open or close the valve. Wafer butterfly valves are used in applications with low pressure and temperature.

Lug butterfly valves have a disc connected to the stem with lugs extending from the sides of the disc. The lugs hold the disc in place, allowing it to rotate and open or close the valve. Lug butterfly valves are used in applications with high pressure and temperature.

Double-offset butterfly valves have a disc offset from the center of the valve body. The balance allows for a more excellent range of motion, making double-offset butterfly valves ideal for applications requiring frequent operation or tight sealing.

Why Use an Actuated Butterfly Valve?


One of the main advantages of using an actuated butterfly valve is that it provides precise control over the flow of liquids and gasses. When the disc of a butterfly valve is actuated, it can be opened or closed at any point between fully open and fully closed. This allows for a much greater degree of control than other valves, making it ideal for applications requiring a high degree of accuracy.

Another advantage of using an actuated butterfly valve is that it is straightforward to automate. Actuated butterfly valves can be controlled by various means, including electric, pneumatic, and hydraulic actuators. This makes them well-suited for applications where automated control is desired.


A final advantage of using an actuated butterfly valve is that they are reliable and durable. When adequately maintained, an actuated butterfly valve can last many years without requiring replacement or repairs. Additionally, they are not susceptible to the same type of wear and tear as other valves, making them an ideal choice for high-use applications.

Conclusion


In conclusion, butterfly valves offer several advantages, making them an ideal choice for many industrial applications. They are easy to automate and provide precise control over the flow of liquids and gasses. Additionally, butterfly valves are very reliable and durable.
