Globe valve is in the big family of stop valve, which is named from it rounded shaped, and can be isolated into two distinct halves by the opening or closing of a disc. Besides, globe valve has elements including bonnet, body, stem, plug, seat ring and cage, seemed to be a little more complex than other valves.

Valves can be classified into two types in terms of the on-and-off wetting. The two types are the stop valves and check valves. The first type is designed with an on, off or fractional on setting. The second type check valves stop the fluid flow in only a single direction. Globe valve is in the big family of stop valve, which is named from it rounded shaped, and can be isolated into two distinct halves by the opening or closing of a disc. Besides, globe valve has elements including bonnet, body, stem, plug, seat ring and cage, seemed to be a little more complex than other valves.

Viewed from the outside of the globe valve, the upper part is a hand wheel. But in most big industrial fields, the manual hand wheel is always replaced by the pneumatic electrical of hydraulic actuator. And there is an important element of the globe valve, which is the baffle. The baffle is parallel to the pipe's length, it splits the inside of the pipe. The working principle of the baffle can be described as below: the baffle has an vacuum-packed opening, which use a flat plug or a disc that is pushed down in the seat or opening parallel to the pipe to break the flow inside the pipe. The disc is joined with a stem. The stem can be seen held by the valve bonnet outside the pipe. When the stem is screwed down by the upper wheel, at the same time, the disc is also be pushed to its seals, finally touch the seat opening.

Sometimes, global valves are said as throttle valves, because they can restrict the flow inside the pipe. When the sealing disc is relocated halfway going to the seat opening, the flow is restricted as the passageway is reduced. We can say that, throttle valves can normatively control the flow inside the pipe. They are quite popularly utilized by water pipes. With these valves, the operators either open the valve partly or open completely,  the water flow can be managed excellently.

Besides, global valves can be installed to against or close with the liquid flow. The situation is: when the liquid flows is against the passageway of closure of the disc, it will be easier to open the valve. Oppositely, when the liquid flow is in the similar passageway that the disc is closing, the flow will help close the seat by harder open it.
