Want this question answered?
The Globe valves are generally used to control the flow rate and ball valve used for open /close purpose only.A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it.
Possibly a ball type
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve
If the purpose of the valve is to modulate flow, a globe valve is preferable. If the valve is only on-off, a gate valve is preferable because of lower pressure drop when the valve is open. As wikipedia , A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. So i think it is a globe valve to use in steam pipeline.
If a globe valve is the same as a ball valve and your question is how does it work to stop the flow of water? There is a ball inside the valve that has a hole through the center in the same direction as the handle. When you turn the handle, the hole closes and seals against the sides of the valve.I Globe Vavle is not the same as a Ball Valve. A Globe Valve has a disc that closes an opening and can be used to throtle the flow. A Ball Vavle is as described above. The Globe Vavles usually have a wheel type valve handle and a ball valve has a lever type handle.
well is htr control valve
A check valve allows for flow in one direction and a gate valve is used for positive shut off and a globe valve is used for throttling
The external housing (shell) of gate and globe valves are similar, but the globe valve is designed to serve as a regulating valve, meaning that it can adjust the flow by the percentage of the opening. However, the gate valve is not designed to regulate flow, but to stop the flow. A gate valve should always be either fully open or fully closed. The main difference is in the form of the inner elements and the form of the flow inside the valves. In addition, the gate valve may have a rising or non rising stem while the globe valve is typically a rising stem design. The direction of flow through a gate valve is not important. However a globe valve has a flow direction indicated on the outer shell (body) which indicates the direction of flow from beneath the seat. In a gate valve, the closure element is a plate or disk which travels parallel to the plane of the seat. The gate in a dam is a well known example. In a globe valve, the closure element is usually called a "poppet", and it travels perpendicular to the plane of the seat. There are specific advantages and disadvantages to each type depending on the application. The application for a globe valve is regulating flow. It is not well suited for full stop isolation. The gate valve is an isolation valve and not designed to regulate flow.
Control valve stop valve inch type valve
gate valve. globes are used for throttling and have far too many turns. ball valves are not made for thick stuff. this question was on the inter-provincal exam they had globe valve, gate valve, diaphragm valve and piston valve. for answers too choose from.

A globe is designed for throttling and NON quick closing thus no hydraulic waves are caused. A ball type uses a ball normally stainless rather then a washer for a positive shut off
