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.
How Valves Work?
Valves are an essential component of any plumbing system, playing an important role in controlling the flow of liquids, gases, and steam. They are also found in a variety of other applications, including industrial and automotive systems. To understand how valves work, it is important to have a basic understanding of their anatomy.
A typical valve is composed of a body, a bonnet, a disc, and a stem. The body is the main part of the valve and is usually made of metal. It houses the other components and contains the inlet and outlet ports. The bonnet is a cover that screws onto the body and is used to seal the valve. The disc is the primary moving part and is connected to the stem. It is used to open or close the valve by blocking or allowing fluid to flow through the ports. Finally, the stem is the part that is connected to the disc and is used to open and close the valve manually or with a motor.
Valves are used to control the flow of fluids, gases, and steam. Depending on the type of valve, the mode of operation may be manual or automatic. Manual valves require someone to make adjustments to open or close the valve. Automatic valves, on the other hand,
