Components

Globe valves have a very distinct globe shape. The disk, valve stem, and the hand wheel are the moving parts in the valve body. The body is available in three different designs depending on the application as well as three different types of disks.

Body Construction

Due to the angles in the globe valve body there is a high level of head loss. Head loss is the measure of reduction in the total head of liquid as it moves through the system. Total head loss can be calculated by summing the elevation head, velocity head and pressure head. While head loss is unavoidable in fluid systems, it is increased by obstructions and discontinuities in the flow path such as the S shape of the globe valve design. The body and flow pipes are rounded and smooth to provide system flow without creating turbulence or noise. To avoid creating additional pressure losses at high velocity the pipes should be a constant area. Globe valves are available in three main body types (although custom designs are available as well): angle design, Y-shaped, and Z- shaped.

Angle: Angle valves are designed so that the inlet and outlet are perpendicular. They are used for transferring flow from vertical to horizontal.

Y-body: Y-body design valves, also known as cross-flow globe valves, derive linear action from the incline between the axis of the inlet and outlet ports. This design reduces the high pressure drop inherent in globe valves. The seat and stem are at a 45° angel with the media flow, for a straighter flow path at full opening. The Y-design also keeps the stem, bonnet, and packing in a relatively pressure-resistant envelop. This valve design is well suited for high pressures and other severe services.
