There is no difference between the butterfly valves themselves, the difference lies in their respective actuators and the applicable working conditions affected by the actuators. Among them, butterfly valves can be divided into pneumatic butterfly valves and electric butterfly valves, both of which are widely used in the market. These two butterfly valves are easily confused because of the difference in driving energy. This kind of valve with structural similarity is more likely to be confused in procurement and use, so buyers need to fully grasp the principles and advantages of the two. Here is a detailed introduction to the difference between them. Let's take a look.

Electric actuated butterfly valve is a kind of valve commonly used in petrochemical, shipbuilding, power station, metallurgy, pharmaceutical and light industry industries. It is mainly used to cut off or control the medium in the pipeline. In the long-term use of electric butterfly valves, it is inevitable that various faults will be encountered, and leakage is one of the more common faults. This article mainly introduces the causes of electric butterfly valve leakage and the corresponding treatment methods.

Ball valve and butterfly valve are the two most commonly used valves. Compared with other valves, the two are simpler and easier to operate, and they play a role in the control of cut-off and cut-off of the medium fluid in the pipeline. The ball valve is a control valve in which the opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve. Butterfly valve, also known as flap valve, is a kind of regulating valve with a simple structure. Butterfly valve can be used for on-off control of low-pressure pipeline medium means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing.

The butterfly valve has a simple structure, small size, light weight, and few components. It is very convenient to open, just turn the switch to 90 degrees. The butterfly valve controls the fluid very well, and can increase or decrease the flow rate at any time. Generally, the valve has a certain resistance when transporting any fluid, and the resistance of the butterfly valve mainly comes from itself, such as the thickness of the butterfly valve body. If you want to reduce the resistance to the fluid, just reduce its thickness.

Butterfly valves are widely used, so the selection and purchase of butterfly valves is particularly important. Today, we will introduce the selection of butterfly valves so that you can buy a butterfly valve suitable for you. The plate of the butterfly valve is installed in the diameter direction of the pipeline. The butterfly valve is simple in structure, small in size and light in weight. It only consists of a few parts, and it can be opened and closed quickly by rotating 90°, and the operation is simple.

Butterfly valve, also known as flap valve, is a kind of regulating valve with simple structure. Butterfly valve can be used for switch control of low-pressure pipeline medium. It means that the closing member (disc or butterfly plate) is a disc, which rotates around the valve shaft to achieve opening and closing of a valve. Today, we are going to introduce what is a butterfly valve to you. We hope that you can have a general idea about it after reading.
