ue 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.ment of the fluid, gas, or slurry that is being controlled.
