Model code of gate valve

The description of the gate valve type is based on the Chinese valve model. It does not include some of the latest gate valve products developed and produced by our company. In the case that there is no uniform standard for new products, we will adopt the enterprise preparation method of the gate valve model. However, for your convenience, versatility and standards, we will try our best to use the Chinese gate valve model.
