Valves

Valve is a mechanical device that modulates, isolates, reverses, or relieves the flow of a fluid within a pressure boundary by positioning a closure member relative to a seat; the pressure‐retaining assembly comprises a body and bonnet with internal trim (disc/ball/plug, seat, stem, cage or guide) and external sealing elements such as packing and gaskets, actuated manually or by pneumatic, electric, or hydraulic drives.

Ball and Butterfly Valves

A ball valve is a device with a spherical closure unit that provides on/off control of flow. The sphere has a port, also known as a bore, through the center. When the valve is positioned such that the bore is aligned in the same direction as the pipeline, it is in open position and fluid can flow through it. When rotated 90 degrees, the bore becomes perpendicular to the flow path, meaning the valve is closed and the fluid cannot pass through.
