Valve Types

We just learned about the Poppet Valve, and we learned about the Ball Valve before that.

There are lots of different Valve Types out there that are made for different reasons.

A Globe Valve has a body that is shaped sort of like a globe, and has a disc that goes up and down to plug the hole and stop the flow of liquid or gas.

A Butterfly Valve has a circle shaped disc in the middle that spins to open or close.

A Gate Valve has a gate that goes up and down to open or close the hole.

A Check Valve is a type of valve that stays closed unless the liquid or gas pushes hard enough to open it, and then it will close again using something like a spring.

A Control Valve is a valve that is controlled by a computer to tell it to open a little or a lot, so that it can control the amount of liquid or gas that is coming through.

Valves can have have a lot more than just two holes or ports also.
Many valves have three or four ports, and some have even more!

There are a lot more types of valves out there. Pretty much any way you can think of to open or close a pipe, someone has made a valve for it.
