A Fluidmaster fill valve works well on gravity fed?

[WaterTight]

The standard ones bundled in a pack with the flush valve from the sheds/screwstation/toolfix don't perform well on gravity fed in my experience.

I've heard one of the 'pro' version has a restrictor you can remove to make it work better?

If so :-

1) Which valve is this?
2) Does it perform well or just a bit of an improvement?

I find these https://www.NoLinkingToThis/p/thomas-dudley-ltd-bottom-entry-fill-valve/7356f
work incredibly well on gravity with their restrictor removed but always good to have a second or third option for when stuff won't fit propers

Thanks

The red top ones I find ok on gravity

I always try and fit like for like on gravity

Do they have a flow restrictor to remove? I'll get one to give a go.

Yes but it's not pre installed

Just loose in the box/bag

I see. And it's better on gravity than the standard one though? I find those too slow.

The Wirquin fill valve (brass tail version) is very good on gravity or mains pressure. Advantage is the float is encapsulated in an outer case, so won’t be affected by touching side of cistern. It comes with a one piece plastic combined filter and restrictor, which the instructions show to cut the restrictor off for gravity pressure or leave as is and push fully into tail.
