To work efficiently, pipes need a way of regulating how much fluid can pass through them; they also need a way of switching the flow off completely. That's the job that valves do: valves are like mechanical switches that can turn pipes on and off or raise or lower the amount of fluid flowing through them.
How do safety valves work?
In practice, that's not quite true. Sometimes it's better for a valve to fail, intentionally, to protect some other part of a system or machine. For example, if you have a steam engine powered by a water boiler in which steam is building up, but the pressure suddenly gets too high, you need a valve to blow open, let the steam escape, and release the pressure safely before the entire boiler explodes catastrophically. Valves that work in this way are called safety valves. They're designed to open automatically when the liquid or gas they contain reaches a certain pressure (though many systems and machines have safety valves that can be opened manually for the same purpose).
What are valves?

What is a valve in a toilet?
A valve is a mechanical device that blocks a pipe either partially or completely to change the amount of fluid that passes through it. When you turn on a faucet (tap) to brush your teeth, you're opening a valve that allows pressurized water to escape from a pipe. Similarly, when you flush the toilet, you open two valves: one (the siphon) that allows water to escape to empty the pan and another (called a ball valve or ballcock) that admits more water into the tank ready for the next flush.
Why is it important to shut off a valve?
It's often critically important for valves that are switched off to allow absolutely no escape of liquid or gas through a pipe to avoid accidents, explosions, pollution, or the loss of valuable chemicals (even a dripping faucet can be expensive if your water is metered). That's why the seal on a valve needs to be perfectly secure and a valve that's turned off must be tightly closed. Turning off a high-pressure flow of liquid or gas by obstructing it with a valve is physically hard work: in other words, you need to use a lot of force to do it. That's why some valves are operated by levers (like the one photographed here, but some can be much longer to give you more turning force) or large wheels (as in the top photo in this article). If really big valves require too much force for a human to supply, they're operated by hydraulic rams .
What is the valve that allows water to escape from the pan?
Similarly, when you flush the toilet, you open two valves: one (the siphon) that allows water to escape to empty the pan and another (called a ball valve or ballcock) that admits more water into the tank ready for the next flush. Valves regulate gases as well as liquids.
