Regulating valve spool
Thread Content
For the Shanghai Guanghui control valve, after taking it apart, I saw that the valve core has this structure: there are threads on the top of the valve core, an internal fixing sleeve (I’m not sure what it’s called), and a wound gasket at the bottom. I want to know how to install that internal fixing sleeve. I took it apart today and am not sure if it was installed incorrectly; I tried turning it back and forth, but there was no difference. Could someone please explain this? It’s a valve with a DN25 size and PN40 pressure rating
You might be referring to a cage-type control valve. Send a picture up.
Remember to take photos of the items before taking them apart… just in case
No, I didn’t take any photos; I forgot. Do you have any photos? I want to see if it’s the same type that I removed
Send a picture so everyone can come up with some ideas
We use Shanghai Guanghui diaphragm valves here; the valve core has a screw
