    name this valve(?)

    Hello all! Amateur question: What are these? I have a boiler heating system, and these are at the front end of two of my heating water loops. It looks like a brass valve, but there's no handle. As you can see, there is a screwdriver-turned bolt. Is this correct? Or is the nuts-looking...
