To understand what valves you need, you need to know what a valve is and how it functions. Valves control flow and pressure within a system. These devices are mechanical and come in different shapes and forms depending on their specific use. Read on for everything you need to know.
Think of valves as operating like a switch, which turns a pipe either on or off to increase or decrease the amount of fluid or gasses traveling through the channel. One example is your bathroom faucet. When the tap moves to open or close flow, the valve releases water pressurized from the pipes. People can open the valve partially or completely to release different levels of pressure, and thus obtain the necessary flow of water.
Machines that handle liquids or gasses are practically guaranteed to have some sort of valve mechanism. These components are essential to everyday items, including washing machines, cars, and kitchen faucets, among many others.
There are several types of valves including ball, butterfly, plug, gate, globe, needle, poppet, and spool valves, among others. A ball valve uses a sphere which sits inside of the pipe to block the flow of fluid or gas. When the circuit is opened, the...
