A Valve is defined as any devices that regulate the flow of gases, liquids, or loose materials through piping or through apertures by opening, closing, or obstructing ports or passageways. These valves are produced in two different methods, 1 – By Forging & 2 – by Casting. And there are many types and they again very on application to application on their wetted parts. This becomes again an very vast field and its types array with regards to many intricate designer models.
