A 3 globe valve is a type of valve that is used to control the flow of a liquid or gas. It is made up of three parts: a body, a bonnet, and a disc. The body is the main part of the valve and contains the inlet and outlet ports. The bonnet is a cover that is used to protect the internal parts of the valve. The disc is a movable part that is used to control the flow of the liquid or gas. The disc is connected to a stem which is operated by a handle. When the handle is turned, the disc moves up or down to open or close the valve. A 3 globe valve is commonly used in industrial applications, such as in the oil and gas industry, as it is able to control the flow of a liquid or gas with precision.
