Basic standards for valves

Author:


Valve standards are divided into mandatory national standards (GB) and recommended national standards (GB/T). The number of the latest standard for valves consists of the code name of the first standard, the sequence number of the first standard released and the year number (year of release) of the first standard. The national standard for valves includes two parts: one is to regulate the manufacturing, structural length, material, etc.; the other is to conduct a standardized search for the structure, size, etc. of each type of valve. Users can look at the corresponding Valve standards. This standard mainly provides a brief explanation of the general standards and technical condition standards for valves.
