Four nuts embedded in cement slab ... what are they ?

If so they might be valves, turned by screwdriver, to balance the flow of heated water to the different loops (rooms) so some rooms don’t get too much or too little heat,
Then “nut” parts are packing nuts around the valve stems. Snug up a little if the stem is leaking.

They are not leaking, in fact I don't think they are even hooked up anymore.

I believe too this was for in-slab floor heating. The is a small house ... kitchen, living/dining, bedroom and bath. Makes sense to have one master valve and three zones. Years later a second bedroom and bathroom were added.
