Regarding the filter model issue

2015-12-24View Original

Thread Content

I’m new to this and don’t quite understand how filter models are designated. In the technical data sheets I’ve seen, there are names like Y41H-16, SY4P-16C, and GL41H-16C – it’s hard to tell them apart. Could you help me find out the rules for naming filter models? I couldn’t find it on Baidu, thanks!

I have never seen filters of the GL type; for the others, one can refer to SH/T 3411-1999 on the selection, inspection, and acceptance of filters for petrochemical pumps, as well as HGJ 532-91 on filters for chemical pipelines.

I found it on Baidu; the national standard valve code is: lol
