The only one you need
Having two types of connecting makes it so I only need to carry one style on the truck. And carry more of them. I used to carry one threaded and one sweat, now I carry 4 of these, simplifying inventory.

It works as advertised.
I used this valve to supply feed water to the primary loop of a solar hot water split-system. The valve is easily adjusted & can be adjusted precisely. It's strong & well made. I'd buy it again.
