HECK NO READ the ASME code or the NBBI Also read up on valves and what they are designed to do.
A "Globe" valve is used for THROTTLING and severely restricts flow
Personally I like using a GATE valve in combination with a ball valve for Blow down applications

How a bottom blow down valve differ from a surface blow down valve?
their difference is very simple. surface blowdown valve is for light impurities while bottom blowdown valve is for heavy impurities such as sludge, etc.
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 function of adjusting ring in spring loaded pressure safety valve?
The function of the adjusting ring is to adjust the blowdown pressure of the safety valve. By ASME rules this must be adjusted to 2% of the set pressure, or a minimum of 2 psi. If the valve is set to lift at 100 psig or less then the blowdown must be set at 2 psi. If higher then it must be set at 2%. Thus, for a safety valve that lifts at 300 psig, the blowdown will be set (at 2%) such that the valve will reseat when the pressure drops to 294 psig. In many states that have adopted ASME rules, these settings cannot be changed except by an authorized safety valve repair shop holding a National Board repair or assembly "V" or "VR" stamp.
Which valve is prefered to use for ammonia tanks a globe valve or a gate 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.
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 a bottom blow down valve differ from a surface blow down valve?
their difference is very simple. surface blowdown valve is for light impurities while bottom blowdown valve is for heavy impurities such as sludge, etc.
Difference between globe valve and gate valve?
The Gate valve is the stop valve & the Globe valve is the fluid Regulating valve.
What is high pressure blowdown?
its blowdown, at high pressure
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 does a fusible link do within an oil installation?
Fusible link is installed on the hydralic line entering the actuator of the Blowdown valve. The frangible element (fusible link) will melt when exposed to a fire and cause an automatic blowdown of the exposed part of the system.
What is the difference between a ball valve and a globe valve?
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
What is the difference between a globe valve and a butterfly valve in terms of application?
Globe is used for throttling

Is balance valve equal to globe valve?
yes
What valve is the preferred valve to use in throttling a gate valve or globe valve?
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve
When was The Tin Roof Blowdown created?
The Tin Roof Blowdown was created in 2007.
