Global Valve is used to adjust the size of the fluid flow rate in the pipe (throttling). The basic principle of operation of the Globe Valve is the perpendicular movement of the disc from its holder. This ensures that the ring-shaped space between the disc and the seat ring is incremental as close as the valve is closed.

By easily turning the valve handle, the amount of substance flow through the valve can be adjusted.
The valve seat is parallel to the flow, making the globe valve efficient when adjusting the size of the flow with a minimum of disc and seat erosion. However, the resistance inside the valve is quite large.

Globe Valve design in such a way, forces a change in flow direction
substances inside the valve, so the pressure drops dramatically and causes turbulence in the valve
alone. Thus, Globe Valve is not recommended to be installed on systems that avoid
pressure drop, and a system that avoids resistance to flow.
