Globe Valve Arrangement Based on Fluid Flow
Disks that close against the direction of the fluid flow are great if you need a quick opening
valve. Disks that close with the direction of the fluid flow are a better a choice if you need a
quick closing valve.
Ball vs. Needle Disk Types
Things like the type of disk used vary based on the situation. For example, ball disks are more ideal
for low-pressure, low-temperature systems more so than a needle disk.
Z vs. Y Globe Valves
The Z type of globe valve is the most common where the disk and seat sit at 90° (perpendicular)
to the pipe axis, however, this often results in a drop in head.
To get around this high-pressure loss, engineers designed the Y type of globe valve where the stem
and seat of the valve seat at 45° to the pipe axis.
Some common applications of globe valves include
Regulating Flow
Globe valves regulate flow in piping systems. They go in the line between a pump and a tank or reservoir. The valve opens to allow flow from the pump to fill the tank, and then closes when the desired level is reached.
Controlling Pressure
Globe valves fit in the line between a pump and a tank or reservoir. The valve allows flow from the pump to fill the tank and then closes once it achieves the desired pressure.
Managing Temperature
Globe valves are installed in the line between a heat source and a heat exchanger. The valves’ opening and closing allow flow from the heat source to enter the exchanger which controls the temperature levels.
Some Of The Available Connection Options For Globe Valve Include
Bolted bonnet connection: It is a simple and least expensive design. However, it requires accommodation of itself to faces that are rotating and bonnet unscrewing may harm the joint faces.
In addition, it needs torque to tighten the joint of the bonnet that is very large for larger globe valves. Because of this reason, this type of connection is not recommended for globe valve sizes that are so large.
Welded bonnet connection: It is made of a material that is welded and the connection may entirely be welded. This type of connection is economical and very reliable despite the operating pressure, temperature, and size of the globe valve.
Flanged bonnet connection: In this, the effort used to tighten the globe valve can be spread sufficiently thus can be made in any operating pressure increase and valve size. This type of globe valve connection becomes increasingly bulky and heavy and high temperatures may creep relaxation thus lowering the bolt load.
Union ring bonnet connection: This type of connection can prevent movement among the faces which are joint during the tightening process. It is mostly suitable for use in large globe valves.
Pressure seal bonnet connection: It can overcome weight problems through tightening the joint by use of pressure.
This type of connection, therefore, becomes tighter when the pressure of the fluid increases.
This globe valve connection type is mostly preferred for globe valves that operate in high pressures and temperatures.
