What is the difference between plug valves and globe valves with plug?
A Plug Valve is a Globe Valve. Very generally speaking there are two major catagories of Industrial Process Control Valves, Sliding Stem and Rotary. Globe Bodies valves fall into the category of Sliding Stem Valves. Butterfly and Ball valves fall into the category of Rotary valves. However there are what is referred as Rotary Plug Valves, whereby a partial sphere has a shaft eccentrically mounted, that rotates into and out of a metal or composition seat acting as a plug. Most plug valves are sliding stem.
Y pattern globe valve advantages over T pattern?
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]
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.
How you will identify the gate valve and globe valve practically?
globe valve. With a spherical valve is closed. Valves can be closed with a round handle.
What is the directional properties of antenna?
omni-directional is the opposite of directional. A directional antenna receives or sends more signal from or to the front than the sides or back.
What is directional valves?
Directional control valves are one of the most fundamental parts in hydraulic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a piston inside a cylinder which is electrically controlled. The movement of the cylinder restricts or permits the flow, thus it controls the fluid flow. Directional control valves are mainly two types: Hydraulic and Pneumatic. Hydraulic directional control valves are for a liquid working fluid (e.g. water, hydraulic oil) and pneumatic directional control valves are for a gaseous (usually air) working fluid.
Are there stop valves designed like globe valves?
Yes, there are.
Why globe valves are mostly used for steam application?
they are best with pressure and they close all the way.
What are the names of the most important directional lines on the globe?
Look at the name of the category you put it in...
How can you build pressure controller by fast response directional valves?
Super glue and duct tape.

How are directional terms significant?
North, south, east, and west are significant directional terms. They are the cardinal, or fixed points, on a compass. They are reckoned in terms of the two poles, North and South, whiich are fixed points on the globe.
Why the energy losses in globe valve due to the fully open valve is greater than losses of gate valve?
Globe valves have a more complex flow path, involving multiple changes in direction, which results in higher energy losses when fully open compared to gate valves that have a straight-through flow path. This increased resistance in globe valves leads to higher pressure drop and energy losses in the system.
