With the deepening of economic globalization, my country's valve industry is developing rapidly.Sanitary Butterfly Valve structural length standards are one of the most important standards in the valve industry. This article will provide a step-by-step introduction to the relevant information about German standard butterfly valve structural length standards to help readers better understand and master this standard.

Step 1: Understanding the Definition of German Standard Butterfly Valves

German standard butterfly valves are butterfly valves that comply with the German DIN EN 593 standard. German standard butterfly valves are rotary valves widely used in various fluid control applications due to their simple structure and easy opening and closing operations.

Step 2: Understanding the Structural Features of German Standard Butterfly Valves

German standard butterfly valves use a central shaft as their axis. Bearing washers are fixed on either side of the valve body. The bearing seats rotate relative to the bearing washers as the valve disc rotates. Valve seats are available in E-shaped and U-shaped shapes, and the sealing surface is made of rubber. German standard butterfly valves offer advantages such as simple structure, light weight, compact size, and corrosion resistance. Step 3: Understand the Definition of the German Standard Butterfly Valve Structural Length Standard

The German standard butterfly valve structural length standard refers to the length of a German standard butterfly valve at a specific nominal diameter and is different from the length of the valve itself. The German standard butterfly valve structural length standard primarily includes Class A and Class B.

Step 4: Understand the Specific Regulations of the German Standard Butterfly Valve Structural Length Standard

The specific regulations of the German standard butterfly valve structural length standard depend on the nominal diameter. Within the nominal diameter range of DN50-DN400, the German standard butterfly valve structural length standard primarily includes Class A, Class B, and Class C. Within Classes A and B, the lengths of Classes A and B must each be less than a specific length (for example, within a DN50 nominal diameter, the lengths of Classes A and B must be less than 125mm and 130mm, respectively). In Class C, the length can exceed the specified length, but the excess must not exceed 10%.

Step 5: Understand the Application Considerations of the German Standard Butterfly Valve Structural Length Standard

In practical applications, the German standard butterfly valve structural length standard should also take into account issues such as installation, maintenance, and explosion protection. In addition, to ensure the sealing performance of DIN butterfly valves, attention should also be paid to the fit between the valve disc and valve seat.
In summary, the DIN butterfly valve structural length standard is an important standard in the DIN butterfly valve industry and is of great significance for the manufacturing, design, and selection of DIN butterfly valves. In practical applications, the appropriate DIN butterfly valve structural length standard should be selected based on the specific situation.
