Valve Stem

We just learned about the Valve Seat.

Another part of a valve is the Valve Stem.

This is the part that sticks up out of the valve, and is used to help open and close the valve disc which lets gas or water go or stop.

There is a valve stem on a bicycle tire that sticks out.
If you hook a pump up to the valve stem, it will push in a pin which will allow air to go in or come out.
