The customer sent an inquiry sheet, in which check valve DE50, balance valve DE25, stop valve DE75, and I want to know what de stands for, because the price of plastic and cast iron is different. What does de usually mean in the industry?
No, DE is DG, and DG stands for nominal diameter of valve
Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).The tube is thin from the metal tube, and the outer diameter of the tube is almost the same as the inner diameter of the tube, so the average value of the outer diameter of the tube and the inner diameter of the pipe is called the diameter.De is the nominal diameter, that is, the outer diameterGenerally speaking, from small to large specifications are as follows de (mm)De20, de25, de32, DE40, de50, de63, de75, de90, de125, de110De160 de200 de250 de315...... Until de800
Back valve, DE50 balance valve, DE25 stop valve, DE75, what do you mean by "de"?Diameter DEThe diameter of a general plastic tube is indicated by DE in EngineeringNominal diameter is the size of all piping accessories in the piping system. The nominal diameter is a convenient round integer for reference and is not strictly related to the processing size. The nominal diameter follows the letter "DN" followed by a number sign.
