Seek standard for the structural length of manual three-way ball valves

Thread Content

Does anyone have the standard length specifications for manual three-way ball valves? I have a three-way ball valve from 1995 that needs to be replaced. Our factory needs standards for the materials we submit; the model is Q44F-16P DN50, but I can’t find any relevant standards. If anyone can send them to me, I would be extremely grateful!

It is basically impossible to design the structural length of this three-way ball valve according to 12221
