Some times even from USA manufacturers it not as clear as it should be.

Apollo Valves (Conbraco) ball valves on the bronze body are "APOLLO 1/2 USA" and "600 CWP".

One version is good for 150 SWP, the other 250 SWP.

How can you tell the difference? What's written on the rubber handle cover.

The 250 SWP is Red. The 150 SWP version is Black.

That rubber handler cover could be removed.

I have been able to buy ball valves with a 150 SWP at Harbor Freight (All Chinese, every day!) for peanuts. They've been in service for a couple of years with only minor problems. Like rusty handles and a need to snug up the packings a bit more often than I would like.
