Serious servo's you're talking about. There is a reason there is a 5 cm handle on an avarage ballvalve. But yes, it is possible.

There are smaller Burkerts of the 5404 series, but those ain't much cheaper.

And I know of 2 alternatives that are a tad cheaper than a Burkert 5404.
1 is a Slovakian brand called Alpha. We had 2.
Those are now in Wedgie and Microgravity. never found a supplier over here that is "reasonable".
The other is a Chinese "semi copy" of a Burkert 5404, those look nice in pricetag, but after P&P and import duties it's not worth the effort.
