What are the differences between butterfly valves and gate valves? Most people outside the industry do not quite understand the difference between the two. In fact, in terms of application, the flow resistance of the gate valve is relatively small. Another name for the butterfly valve is the flap valve. The function of a butterfly valve is to close the switch in low-pressure pipelines. Butterfly valve enterprises can control the presence of many things, such as air and water, as well as various corrosive substances in society. In the relevant pipelines, it mainly serves the functions of mediation and cutting. The opening and closing part of a butterfly valve looks like a disc butterfly plate in appearance, which can rotate around the shaft plate inside its body, ultimately achieving the effect of closing and adjusting.

The butterfly plate of a butterfly valve is driven by the valve stem. If rotated 90 degrees, the program will be closed. The flow rate of the medium can be controlled by adjusting the deflection Angle of the butterfly plate.

The working range of butterfly valves and gate valves:

Butterfly valves have a wide range of applications, such as in the natural gas and natural gas industry, liquefied petroleum gas and cold and hot air industries. In the construction industry, butterfly valves can be used to convey various corrosive media and also for regulating and phase media.

The research on the role of gate valves here is relatively simple. They can only be fully open or fully closed. At the Angle of the sealing surface, it is easy for workers to cause deviations. Therefore, this type of gate valve is also called an elastic gate valve.

When the gate valve is closed, only the pressure generated by the medium can achieve the sealing effect on the sealing surface. Most gate valves are forcibly sealed. When the gate valve is closed, external force is used to ensure the sealing performance of the relevant sealing surfaces.

What are the differences in the movement methods between butterfly valves and gate valves?

When in motion, the gate plate above the gate valve works together with the valve stem, and it is also known as an open stem gate valve. When passing through the guide groove above the valve body, the rotational function can be converted into linear motion. When the valve is opened, the fluid passage cannot be monitored. When the full valve is opened, it can be determined according to the position of the gate plate. When manually driving the valve stem, the relevant gate plate can be lifted. This kind of valve is called a concealed stem gate valve.

After reading the above introduction by the butterfly valve manufacturer, do you know the differences between butterfly valves and gate valves? It is hoped that the content introduced by the butterfly valve manufacturer today can help you better understand the differences between butterfly valves and gate valves, so as to better distinguish and use the two types of butterfly valves.
