The American standard gate valve is a valve designed according to the American API and ASME standards, mainly used in the petrochemical industry. The elastic seat sealing gate valve of this valve uses the compensation effect of the elastic gate to produce a small amount of elastic deformation to achieve a good sealing effect, and overcomes the problems of poor sealing and rusting of general gate valves. So what are the differences between the American standard gate valve and the German standard gate valve?

In terms of standards, there are many differences between American standard gate valves and German standard gate valves, which are mainly manifested in the following aspects:

1. The unit of nominal diameter of German standard gate valve is mm, while the unit of nominal diameter of American standard gate valve is in (inch).

2. In terms of flange standards, there is also a big difference between the American standard gate valve and the German standard gate valve.

3. There are also differences in the length of the structure.

4. There are also differences in the pressure level units, the German standard is MPa, and the American standard is LB.

5. The sizes of American standard gate valve, globe valve and German standard valve are also different.
