Seeking help regarding valve information
Thread Content
Hello everyone. The company has sent me a product catalog of valves for review. I noticed that one of the valves is designated as D363H10C IN, with a range of 4–48 DN and 100–1200 in terms of size. I know what type of valve this is, but I’m not clear about the relationship between IN and DN. IN seems to indicate that the valve is imported, but if IN is 4, then the corresponding DN value should be 100 – this ratio seems too large. Moreover, I saw that there are no units listed after IN in the product catalog, while DN is expressed in mm. How should I understand the relationship between these two values? I would be very grateful if someone from Haichuan could give me some guidance
IN should stand for inch; 1 inch is actually equal to 25.4 mm. A nominal diameter of 1 inch corresponds to DN25, so 4\" = DN100 and 48\" = DN1200 – that makes sense.
The conversion between inches and DN isn’t difficult; it relates to the diameter of the valve
iN stands for inches; 4in means DN100
So that’s how it is. I finally understand now. Thank you, expert!
Thank you. When using Baidu IN, it referred to imported products; it seems I misunderstood. Thank you
