1.What is the Globe Valve For Pipe Fitting

Globe valves are used primarily in situations where throttling of the commodity is required. Globe Valve For Pipe Fitting by simply rotating the handwheel, the rate at which the commodity flows through the valve can be adjusted to any desired level. Having the valve seat parallel to the line of flow is an important feature of the globe valve. This feature makes the valve efficient when throttling commodities as well as yielding minimal disk and seat erosion. 
This configuration, however, creates a large amount of resistance within the valve. The design of the globe valve body forces the flow of the commodity to change direction within the valve itself. This change in direction creates substantial pressure drop and turbulence. The globe valve is therefore not recommended when flow resistance and pressure drop are to be avoided.

2.Where will the Globe Valve use

Globe valves are used in the oil and gas industry for fluid regulation or throttling. Cavitation as the main operation problem associated with globe valves as well as some of the mitigation approaches have been discussed in this chapter. Different types of globe valves such as needle, straight pattern, and Y-pattern. Some aspects of the valve design such as wall thickness, bore, face-to-face dimensions based on international standards such as API and ASME have been included in this chapter. Readers can get practical information about the design of different components of this type of valve such as body, bonnet, yoke, steam, seat, backseat, etc., that has been explained in this chapter. This chapter contains many pictures of globe valves during manufacturing, assembly, and testing such as pressure, fugitive emission, or flow capacity measurement testing.


3.How does the Globe Valve For Pipe Fitting work

When the Globe Valve For Pipe Fitting  is actuated to open the disk will perpendicularly move away from the seat. When compared to a gate valve, a globe valve for pipe fitting generally yields much less seat leakage. This is because the disk-to-seat ring contact is more at right angles, which permits the force of closing to tightly seat the disk.
Globe valves can be arranged so that the disk closes against or in the same direction of fluid flow. When the disk closes against the direction of flow, the kinetic energy of the fluid impedes closing but aids opening of the valve. When the disk closes in the same direction of flow, the kinetic energy of the fluid aids closing but impedes opening. This characteristic is preferable to other designs when quick-acting stop valves are necessary.
