The valve is actually for the dishwasher and is commonly known as the dishwasher air gap. An air gap's purpose is to prevent drain water from the kitchen sink backing up into the dishwasher, contaminating your cleanly washed dishes.
What Is That Metal Thing? The metal thing in question is a small, cylindrical metal tube that sits next to the faucet on your kitchen sink. Reddit user @dominostracker wondered the exact same thing, and according to a few wonderful human beings who took the time to answer, that thing is an air gap.
Shut-off valve or stops: Often featuring an oval-shaped handle attached to a flexible braided metal line, a shut-off valve is located near a sink to help you control the flow of water. By turning the shut-off valve, you'll control the supply of water to the sink without turning the water off for the whole house.
“That thing” is actually called an air gap, and it prevents wastewater from siphoning back into the dishwasher, which can occur when sinks become clogged and no air gap is present. Without an air gap, contaminated water could be sucked back into the dishwasher, dirtying your clean dishes and making you ill.
Tailpiece: Connects the drain opening to the P-trap. It serves as a connection between the drain stopper assembly and the P-trap, facilitating the flow of water from the sink to the home's waste system and sewer line.
An escutcheon is a pretty metal piece used to hide a hole in your wall where a pipe comes through. They can be found behind your faucets, showers, toilets, and under your sink. During any bathroom renovation, escutcheons are either removed to install new fixtures, or they are completely replaced.

The dishwasher air gap is a chrome or stainless steel cylinder fitting that can be found at the back of the sink near the faucet.
A faucet aerator on a sink looks and feels like a mesh screen disk.

The extra smaller faucet may be an instant hot water tap. Look for a tank under your second faucet with a cord into an outlet or junction box that helps keep the water hot. You don't have to wait for the hot water to travel all the way from the water heater to your sink.
Faucets experience a lot of friction from running water and everyday use. A locking nut or screws keeps a faucet firmly attached to the sink.
A cache aerator (1) is "hidden" even with the end of the spout. Look on the end of the aerator for a circle of notches, like the crenulations on top of a castle. A small tool called an aerator wrench (2), which came with the faucet, is used to remove the cache aerator.

The valve is actually for the dishwasher and is commonly known as the dishwasher air gap. An air gap's purpose is to prevent drain water from the kitchen sink backing up into the dishwasher, contaminating your cleanly washed dishes. Now that you know what it is, how does it actually work?
Air gaps have no moving parts, so they cannot fail. They work on the principle of simple physics. Water cannot siphon back through an unpressurized gap of air. If the drain tube becomes clogged the discharge water from the dishwasher will simply spill out of the holes in the air gap's heading.
Nintendo Switch 2 is finally confirmed. After literal years of unverified rumors, dubious leaks and copious amounts of online speculation, Nintendo has lifted the lid on its next-generation console, and it's the Switch sequel the majority expected (and many of us wanted).
A countertop air switch uses the pressure of air turn on or off your garbage disposal. And while at first glance you might not know exactly what it is, this button by the sink is quickly gaining in popularity for its good looks and advantages over the traditional wall switch.
