Pretty sure the Pegler lever valves available from Screwfix are steam rated.
It would seem you are correct: Pegler Ball Valve Red 15mm - https://www.NoLinkingToThis/p/pegler-ball-valve-red-15mm/21289
Anything decent with ptfe seals , just avoid cheapo.
Thanks, its so annoying. The valve leaks really slowly until it drains the top of our thermal store which is where our DHW coil sits. The family get a bit upset with cold /warm bathsYou need one that has a declared temperature rating over 80c.
That would usually exclude anything from Screwfix etc as they don't appear to give ratings.
Something like this which is up to 110c, (various sizes available.)
