Y pattern globe valves allow probably less pressure drop as compared against the T pattern globe valves. I do not have experimentally proven results for this. However the flow pattern in Y Globe valve is more "linear" while that T pattern is more "zigzag". Secondly, height of the valve from its flow bores' center line till top of the hand wheel is less in Y Globe Valves, as compared against the T Globe Valves. This gives compactness to Y Globe Valves - which is beneficial in pipings where space is a constraint. [by Ganesh Devale, Pune - India]

How to repack a globe valve?
The packing is located under the handle there is either a stuffing box or a nut over the valve stem
What are the uses of a globe valve?
To throttle the medium being used as a globe is NOT a positive shut off 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. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
What are some problems with a globe valve?
advantages of a globe valve * you get instant access to the supply: only a 90 degree turn to open fully * less maintenance is required to the valve as you won't have to re-seat it disadvantage of a globe valve * it is harder to finely adjust the flow of your substance compared to a gate valve: a gate valve requires many more turns to fully open and close than the single 90o "part-turn" required on a globe valve
What does overhead valve mean?
It's a valve that's over your head
What are the advantages of a hovercraft?
The Advantages are that Hovercraft can fly, or more suitably, hover over water and land, can go over rough terrain and does not pollute as much as cars.
Where should the pressure enter a globe valve?
Over the seat

What are two advantages of the globe over the precipitation map of Florida for understanding characteristics?
A globe is tells you the continents but actuall a map is better because it is smaller, cheap,and every detailed.

What are two advantages of the placental pattern of development over the marsupial pattern?
More mature newborn Less risk to immature foetus
What advantages does a thermostatic valve have over a capillary tube?
Thermostatic expansion valve allows more refrigerant into the evaporator coil during a hot pulldown it allows the evaporator to reach peak performance faster
What are the advantages of using a globe show the earth surface?
One advantage to using a globe is that you can more accurately determine distances than you can with a flat map. Flat maps distort the spherical surface and that distortion can be significant over long distances.

What advantages does a globe have over a flat map?
A flat map exaggerates certain countries close to the poles. A globe shows the bodies of land in their actual size. For example: Greenland looks huge on a flat map, but looks much smaller (its actual size compared to the other countries) on a globe. Next, lines of longitude and latitude are more accurate on a globe.
