Gate Valves are used for On-Off control
whereas Globe Valvesin addition can also be used for the flow regulation.
Gate valves offer very little resistance
to fluid flow in fully open position and also have small pressure drop across
the valve. Globe valves on the other hand have a high pressure drop even in
fully open conditions and offer substantial resistance to fluid flow.
Gate valves of the same size are cheaper
than globe valves.
Gate valves because of their design have
very little fluid trapping in the line but the globe valves have a larger amount
due to the direction of flow.
Gate valves are unidirectional and can be
put around in any way. The globe valves are not.
