The electric butterfly valve can be operated from full open to full close by only 90 degrees. Although the valve stem of the butterfly valve has no self-locking capacity, a turbine reducer can be installed on the valve stem for the positioning of the butterfly plate. Why do you use this thing? It is very simple. With it, the butterfly plate will have self-locking ability, which can stop at any position, and even improve the operating performance of the valve. It is not difficult to see that electric butterfly valves have their own characteristics. In various butterfly valve products, understanding the characteristics of butterfly valves is helpful to use. In many cases, we will refer to the use and performance of butterfly valves for combination. Next, we will talk about the application of electric butterfly valves in detail.

The butterfly valve was invented in the United States in the 1930s, introduced to Japan in the 1950s, and was widely used in Japan in the 1960s, but popularized in China after the 1970s. At present, the butterfly valve generally above DN300 mm in the world has gradually replaced the gate valve. Compared with gate valve, butterfly valve has shorter opening and closing time, smaller operating torque, smaller installation space and light weight. Taking DN1000 as an example, the butterfly valve is about 2T, while the gate valve is about 3.5T, and the butterfly valve is easy to be combined with various driving devices, with good durability and reliability.
