What is a Valve? A valve is a device that directs and regulates the flow of fluids by closing, opening or partially obstructing different passageways. They are seen as fittings but are usually discussed as a separate category. As such, valves have many uses and come in different types and forms. For example, in an open valve, the fluid flows from higher to lower pressure.
Valves are additionally used to control water for irrigation, other controlling processes, on/off pressure control and so on. Even things like aerosols have a valve built in them.
As previously mention, there are many types of valves and they all are made to do a specific job. Check out the video to find out more about them!
