What is the structural length of the valve?

The length of the metal valve structure is what is it?

Foreign "Metal Valve structure length" standard modification adopted ISO5752-1988 "flange pipeline system metal valve structure length" international standard, compared with, increased the welding end, clip type, internal thread, external thread structure basic length series and structural length of various valves, more scientific and reasonable, can be international standards, easy to use.

Structural length of the valve from Betu 1-1 to Figure 1-3.
