The standards for marine valves can significantly improve the quality of valve products and the efficiency and economy of pipeline installations. In various situations, it is of great help to marine valve users.

Marine valve standards can generally be divided into basic standards, material standards, product standards, component standards, structural element standards, inspection standards, etc. The basic standards mainly include markings, supply requirements, structural length, connection dimensions, appearance requirements, etc

Our most commonly used standards are: GB/T584、GB/T585、GB/T586、GB/T587、GB/T588、GB/T589、GB/T590、GB/T591、GB/T592 Wait. These standard valves can be divided into 2-6 varieties according to their nominal pressure. For the convenience of construction, we usually choose the same nominal pressure rating.
