The Best Designs For Steam Jacketed Valves

It is very important to carry out steam jacketing on valves. This process is normally done with the purpose of providing appropriate migration of temperature. This is done on steam jacketed valves by fully or partially covering them for proper transfer of temperatures from one point to the other. Steel and stainless steel are always used in this process before helium is used to test their effectiveness.

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.

Most designs normally involve coverage of the valves from one end of the equipment to the other. No part is left bare. This type of valve coverage is called a full jacketed valve. It comes in several forms depending on the manner of coverage.

A variation of this process involves over-sized flanges. The flanges are deliberately elongated to easily bring them into contact with the heat producer. This is always with the objective of ensuring that enough heat is transferred to prevent seizure and crystallization.

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.

Another way of fully jacketing, though not a genuine way of covering, is use of oversize flange BV. It is also a very critical process in this field. The whole body of this equipment is covered. Only parts at the center are not covered. Mostly, valves covered this way contain two or three ports on each jacket. Normally, they are made as short or long E-E dimensions.

In Partially jacketed equipments with standard flanges, all the central parts on the valve are covered while the sides are not. The sides are always left bare, and, therefore, directly come into contact with heat. There is always no need for covering the sides. Some valve designs do not require to be wholly 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.

Summarily, it is important to take some issues into consideration when looking for good valves. One should consider the materials used; steel and stainless metals are good since they cannot be corroded. He/she should also determine whether the design can suit his/her needs. Some valves may not be properly jacketed, and, hence, can leak a lot off heat.
