How to convert the valve model ‘inch’ to nominal diameter

2016-08-28View Original

Thread Content

For example, 4 inches corresponds to DN100, and 3 inches corresponds to DN80. How is this calculated?

The valve size ‘inch’ refers to inches, with 1 inch being 25.4 mm.
Reply #32016-08-28
1 inch of the valve = 25 mm; inch * 25 = DN (rounded up)

There is no direct conversion between the nominal diameter in inches and that in mm, as the standards are different.
