Landing valves and hydrant valves are like the main players in a fire-fighting team. They're essential parts of a system designed to tackle fires effectively.

Now, the term "landing valves" comes from where they're usually placed: on risers in buildings, often on staircase landings. This makes them easy for firefighters to reach in case of a fire emergency. Think of the landing valve as the captain of the hose system. It's a manual valve that lets you control the flow of water in your firefighting setup. When you need to get water flowing, you just turn the handle of the landing valve in one direction.

This is super important, especially in tall buildings where water pressure matters a lot. So, whether it's a small fire or a big emergency, landing valves are there to help keep things under control.
