How big is it?

Reply #22016-10-20

Imperial system, DN40; 1 inch = 24.5 CM, so 1.5 inches is approximately 40 CM

What organization is this from? 1 inch = 25.4 mm; you’ve essentially enlarged it by nearly 10 times.

\"Cun\" is the term commonly used in our industry; \"Cun ban\" corresponds to the nominal diameter DN 40

In metric and imperial units, 1 and 1/2 is inches ln. It is DN40. Used for valves

Isn’t that right? 1 inch = DN25 diameter = 25.4 mm, no problem at all

Check whether the value indicated for each floor is correct: 1 inch = 24.5 CM

The notation is: 1-1/2"

There are quite a few such markings on the device; they indicate inches, and it’s a DN40 valve
