Dear peers,

API standard 600  is written for Steel Gate valves. it is my impression that this standard is for full port gate valve based on my reading for the scope, page 1. Some gate valve manufacturers state that their products meet API 600 standard.  Does this mean their gate valves are full port gate valves if the valves meet API 600 ?  After I read thru API 600, I did not see the description of port diameter against NPS as I expect port diameter must meet certain requirement vs NPS in order to be qualified as full port. If API 600 is for full port gate valve, is there a API standard for regular gate valve ?


Hope some peers out there could share your understanding of API 600 and put me straight for full port gate valve vs regular one.
