Globe valves derive their name from the rounded bodies/spherical shape and are widely used in fitting industry to regulate fluid flow in both on/off and throttling service. These linear motion valves consist of moving parts including disk, the valve stem, and the hand wheel.

The stem is used to connect the hard wheel and the disk; the valves are threaded and fit into the threads of the valve bonnet. These specialty valves allow fluids to pass the spaces between the edge of the disk and the seat when open.

Types of Globe Valves
These valves are available in three main body types, namely : Angle Design, Y-design and Multi-piece Design. Angle valves are a type of globe valves, so designed, that the inlet and outlet are perpendicular, for transferring flow from vertical to horizontal. Y-design valves derive linear action from the incline between the axis of the inlet and outlet ports. The inlet and outlet are not of single piece construction. These valves offer precise throttling and control and have high-pressure limits. They also offer a low coefficient of flow and are however not good selections in applications requiring cleanliness or sterility.
