Behold, a thing of beauty. It’s clearly meant to screw onto some heavy, black pipe. You know, the kind used for sprinkler systems and home heating oil tanks. But… there’s brass. And some fiddly bits. And no obvious opening?

It turns out that this is a wonderful invention that is still essential today. While you probably won’t have one in your home, there are many industries where such a thing is needed, and you’d be very happy to have this.

Hint 1: 

Spoiler

It has many names, but one is related to a Boston disaster.

Answer:

Spoiler

It’s called a “molasses valve” or “gate valve.” It allows you to precisely control how much of a thick liquid will come out of a large container like a barrel or vat. Some models use springs to self close. The brass has an oval cut to allow smooth flow with no splashing. Somehow. The Boston hint related to the great molasses flood. NOTE: I ran across one in use!
