Can anyone tell me what is the industrial application for globe valve?? Please help. I tried to search in the Net but couldn't get.
I will rstrict myself to only the types other wise the selection criteria are many. GLOBE: These are used for controlling a process parameter loop. They cause medium pr. drop are ideal for clean fluids. The shape of the stem is contoured to get the desired characteristics. The repeatability of the type in flow control make it ideal for closed loop control. BUTTERFLY: These are low pr drop devise that are used primarily where u can't allow higher pressure drops. Good for clean fluids in on/off service. Even allowed for gases. it opens/shuts faster than other types of valves. Sealing characteristics are not as good as ball valve, particularly unsuitable for fluids containing solids.
Application Of Globe Valve
The web page of the attached link has some good section drawings of the various valve types. Whereas ball and gate valves are designed as shut-off valves, and only operate efficiently fully closed or fully open, Globe valves, due to their internal design, can operate fairly efficiently in a partially open position to throttle or control the flow rate of liquids. They are used to control flow rates when mixing fluids or in batching operations where the fluid flow may need to continuously adjusted. The valves can be operated manually or automatically depending on the process.
