New strainer needed. What is the proper name for this?

[spinnerc41]

Removed this from a valve in my heat pump it needs replacing as the top ring now loose.
Does anyone know what its called and where to get one.

Look for a name on the valve you removed that from, only the valve manufacturer will have the correct one.

you could clean it up and solder it onto the filter mesh

As above the strainer manufacturer should have spares , but it could be repaired as Shaun says its a basket mesh filter you could try online.? I found this company with a simple search on Google
