The standard of marine valve can improve the quality of valve products   the efficiency  economy of pipeline installation, which has a great influence. In many cases, it is of great help to the users of marine valve.

　　Marine valve standards can be generally divided into basic standards, material standards, product standards, parts standards, structural elements standards, inspection standards, etc. The basic standard mainly includes the mark, supply requirements, structure length, connection size, 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, etc. These kinds of standard valves can be divided into 2-6 varieties according to the nominal pressure. For the convenience of construction, we usually choose the same nominal pressure class.
