DIN flange ball valve is a German (DIN) standard full bore flange ball valve. The main material is stainless steel or carbon steel. It can be operated through a handle, worm gear, pneumatic actuator, or electric actuator. Stainless steel DIN flange ball valve is a high-performance industrial valve widely used in fields such as petroleum, chemical, pharmaceutical, food processing, and shipbuilding. This ball valve is made of stainless steel material, which has excellent corrosion resistance and mechanical strength, and can maintain long-term stable operation in harsh environments. Its design complies with DIN (German Industrial Standards), ensuring perfect matching with various piping systems through precision manufacturing and strict quality control. This valve adopts a flange connection method, which has reliable sealing performance and convenient installation characteristics. The sealing form between the sphere and the valve seat is usually a soft seal or a hard seal, which is suitable for controlling and cutting off high temperature, high pressure, and corrosive media. The valve stem design is equipped with an anti blowout device to enhance operational safety. Spheres designed with full or reduced diameters can effectively reduce fluid resistance and improve work efficiency. In addition, stainless steel DIN flange ball valves also have the characteristics of compact structure, flexible operation, and easy maintenance. They can be driven manually, pneumatically, or electrically to meet different working conditions, making them an ideal choice in modern industrial pipeline systems.

The main standard for DIN ball valves is DIN 3357: This is a standard for the design and manufacture of ball valves, covering requirements for overall dimensions, temperature and pressure ratings, and flange drilling. DIN 3202: This is a standard for the structural length of ball valves, which specifies the specific dimensions of different models of ball valves in terms of their structures. DIN 2542-2545: This is a standard for connecting flanges of ball valves, ensuring the reliability and sealing of flange connections. DIN 3230: This is a standard for ball valve testing and inspection, ensuring that the quality and performance of ball valves during the manufacturing process meet requirement 1.
