So where is the butterfly valve size information displayed? How do you look at the size of the butterfly valve? For friends who have never been in the valve industry, it is a big problem. This article will take you to learn how to look at the size of butterfly valves.

Whether it is purchasing a new butterfly valve or replacing an old butterfly valve, we need to confirm the parameter information of the butterfly valve. Among them, the size information of the butterfly valve is one of the very important parameters. If the size of the butterfly valve is wrong, it cannot be installed or Replacement seriously delays the progress of the project. So where is the butterfly valve size information displayed? How do you look at the size of the butterfly valve?

For friends who have never been in the valve industry, it is a big problem. This article will take you to learn how to look at the size of butterfly valves.

First of all, the diameter of the butterfly valve is expressed by DN in the parameter specification. For example, DN100 means a butterfly valve with a diameter of 100mm. Usually this diameter refers to the inner diameter of the valve. The caliber size is generally marked on the valve body of the butterfly valve and on the nameplate, which can be obtained by observation. If you want to replace the old butterfly valve, and the diameter of the old butterfly valve cannot be directly identified because of its corrosion, you can only take a ruler after the valve is disassembled.

Secondly, the size of the butterfly valve is often mentioned as the structural length, or the thickness of the butterfly valve. This structural length dimension is generally not shown on the model, valve body or nameplate, and it needs to be agreed between the designer and the manufacturer. Some people may ask, isn't the butterfly valve a standard part, and how much diameter corresponds to how much structure length. In fact, there are standards for butterfly valves, but there are many standards for butterfly valves, such as national standard, German standard, American standard, Japanese standard, etc., and the length of the structure of different standards will be different; in addition, some pipes are special and require special customized structural lengths by the manufacturer. satisfy.

The manufacturer will have relevant drawing information for the specific length and size of the butterfly valve structure. If the buyer is not sure about the size, you can compare with the installation size after consulting with the manufacturer. The following will introduce you to the wafer butterfly valve and the flange butterfly valve part of the caliber The corresponding structural length and size information is for your reference.
