Valve designers have come up with techniques of manufacturing both partially and fully jacketed designs. These steam jacketed valves are usually meant to provide reasonable temperature migrations. This occurs whenever steam comes into contact with the valve. Standardized designing uses steel metal and stainless steel. Later the valve is tested with helium.
Buyers often consider several key elements before buying such valves. Among these elements are; whether the type of valve needs to be partially or fully jacketed, the type of bolts used, the number of holes, material used and the size of those valves. All these factors are essential in the effective working of valves.
Fully jacketed valves are those covered from one end to the other. Most parts of their bodies are covered. There are also several variations of this type of jacketing depending on the needs of the owner. The opposite design is referred to as partially jacketed. In this one, only some parts are covered and not others.
Full covering with oversize flanges occurs in valves whose flanges are lengthened. They are normally made to be longer than the normal size. When this happens, the valve is capable of coming into direct contact with the source of heat. This design ensures that there is enough migration of heat to keep crystallization and seizure at bay.
Full jacketing can also be done using standard flanges. This occurs when the jacket runs from one flange end toward the other using threaded insertions bound on the back and front parts of this valve and inserted into bolt holes on the equipment. It will then be wielded to the external diameter of the flanges then into the the equipment itself. Normally, this process uses threaded studs.
There is also another fully jacketed design that makes use of oversize flanges BV. This device is usually not a genuine jacket category. However, it is very popular in this industry. The valve is fully covered except flanges on the central parts of the equipment. They normally have two to three ports on every jacket. Manufacturers usually fabricated these models as either short or long E-E.
In partial jacketing where standard flanges are used, only the central parts of these valves are heated. The sides and the other parts are left to come into direct contact with heat. This style is commonly applied in valves where the sides do not need to be heated directly. It is good to do this to valves which do not necessarily need to be fully jacketed.
As discussed in the introductory section, steel and stainless metals are always the best options for this process. They are commonly used due to their strength and their corrosion proof quality. They are normally tightly fitted together to prevent heat leakages for efficiency.
In a nutshell, one needs to put several significant issues into consideration when deciding on the type of valve to use. He/she has to know the best material required in their manufacturing; stainless metals, precisely steel. Steel do not easily get corroded, and is very strong for this job. He/she also needs to use his/her preferences when choosing between partially and fully jacketed equipments. If these factors are not put into consideration, one might easily pick defective valves which might lead to big loses.
