The term “jacket” refers to a void or space between the width of the jacket material and the thickness of the valve body that allows media such as heating oil, heating water, steam, and cold water to pass through or flow into the pipeline without interruption. When building a jacket, a large enough gap must be included to allow flow media to travel through the hollow of the jacket in a circular path. For entering a medium, there is typically an inlet connection, another connection is for the media’s output, and a third connection for the drain is provided by jacketed valve manufacturers. Although it is not a typical procedure, drain connections can be made if necessary.

The term “Jacketed Ball Valve” refers to the valve body that is surrounded by a jacket. The jacket may be entirely cast with the valve body or fabricated (welded) from the outer body. Choosing a manufactured or cast version of the jacketed valve varies on the feasibility of castings. The construction of different jacketed valve types and their users rely on the factors like flow medium, system pressure & temperature, functionality, and operation of the valve. Jacketed valves are widely known for being specifically created for use with media fluids that may seize or crystallize. It is necessary to highlight that extra heating and cooling techniques should not have an impact on these valves.

The basic function of a jacketed valve is to keep the medium in the pipeline flowing freely in a liquid or flowable state with the addition of a jacket around the valve body. In industries where materials like sulfur, asphalt, coal tar, bitumen, and viscous media harden at room temperature, steam or hot oil jackets are typically used to alter pipelines, valves, and pumps.

Due to enough simple bolting space at the flange, nearly all jacketed valve flanges are one size larger. Manufacturing the valves of the same size as a flange line is also possible, but the jacket would then be of the half or partial type.

Besides this, jacketed valves operate in a manner that is generally comparable to that of conventional valves. Any valve, including a ball valve, plug valve, control valve, needle valve, slider valve, pinch valve, manifold valve, etc., can have jackets added to them. However, ball valves are typically used with jacketed valves because they are simple to operate and provide greater temperature control for flowing fluid.

What is a Jacketed Ball Valve?

To avoid flow media crystallization or seizing, the Jackets guarantee continuous valve temperature control of the process medium. The Jacketed Ball Valve has been carefully designed to enable the flow of hot oil or steam over the valve ball and body components, maintaining the media’s liquid nature. This is particularly true when the system is carrying the materials like bituminous, asphalt, chocolate, liquid sulfur, molten sulfur, lactum, and soap. Moreover, by getting rid of pockets, the efficient flow of media is guaranteed.

Thermic fluid oil, steam, and hot water are a few fluids that may be utilized as a heating medium in jacketed ball valves. After the construction of or welding of jackets to valve bodies, all jacketed ball valves are inspected. Cast carbon steel and stainless steel are utilized to create the typical jacketed ball valve. On the customer’s request, jacketed ball valves can also be produced from other unique materials. Threaded end and flanged end connectors are two options for connecting the valve to the pipeline. Jacketed ball valves can be manually opened or closed or driven by valve actuators (electric or pneumatic actuators).

Working: Jacketed Ball Valve.

Jacketed ball valves are built similarly to standard valves that are employed in different industries. Simply put, the jacketed ball valves include void space or jackets inside of them that allow liquids or steam to pass through and regulate the temperature of the fluid that is flowing through the valve.

Based on the thermal regulation and fluid flow rate, these jackets are built into the valve body in a variety of shapes and sizes. The media must be supplied into the jacket via a separate circulation mechanism. Depending on the requirement of the flowing media, the jacket medium might be either cooling or heating.

Working: Jacketed Ball Valve.

The jacket media from the pump is pumped into the valve’s jackets, where it is used to chill or heat the fluid that is passing through the valve. The used media is gathered from the jacket’s outlet and filtered by the strainer to remove any contaminants. The media is then sent to a heat exchanger for heating or cooling, depending on the situation, and the cycle continues. The medium is replaced after a certain number of cycles because it loses its thermal characteristic. Typically, the jacketed valve uses one or more of the following media: steam, heat transfer oils, water, refrigerants, etc.

The jacketed ball valves are commonly offered with flanged ends in 2-way or 3-way variants. For particular applications, valve ends that are bolted or fabricated are also available. Jacketed ball valves can handle a variety of viscous fluids, such as those that freeze at ambient temperature or those that demand temperature control.

Types: Jacketed Ball Valve.

There are many different types and combinations of jacketed ball valves. Considerations for jacketing include flange size, complete or partial covering, the kind and position of connections for the heating medium, bonnet jackets or increased heating coverage for particular regions, and construction materials. Manufacturers should carefully evaluate the temperature requirements of the process, as well as the flange diameters and ball valve type to be utilized, before specifying constructed jacketed valves. For instance, the majority of big, full-port ball valves are only offered in two- or three-piece designs.

Based on the purpose for which a jacketed ball valve is going to be used, there are two types:

  1. Heating Jackets: In need of keeping the process medium flowing properly, it is necessary to use heating jackets where the system temperature should be managed through the valve. The heating jacket can be especially important if there is a chance that media will become trapped inside a closed valve since it will help to keep the process temperature stable and stop the contained product from hardening. We frequently receive inquiries from customers who need to replace a seized unheated valve with a jacketed version but have not thought about this possibility. Chocolate manufacturing, sulfur extraction, pharmaceuticals, and fertilizer industries are examples of businesses that frequently employ jacketed valves.
  2. Cooling Jackets: In this type, the temperature of the process medium is controlled and maintained via cold jacketed ball valves. Where the temperature of the process medium affects the entire system and process of the plant, cold jackets are used to prevent reaching the maximum temperature while the plant is still operating, which is not achievable with ordinary valves.

Jackets could be totally welded onto the valve, making the valve’s outer surface into the inner surface of the heating jacket. Alternative valves include clamp-on design jackets that make it simple to change the valve without replacing the heating jacket.

Effective heat exchange is essential for removing any potential thermal deformation pockets in order to prevent a negative reaction to the product flow. The heating or cooling medium maintains contact with the valve body’s outside surface, allowing for trustworthy heat transfer. Other materials could also be utilized in addition to the steel or stainless steel that is typically used for jackets. All jackets are tested underwater using helium gas at 325 PSI following the completion of the fabrication operation. When the valve is installed with the jacket, the process end is tested in accordance with API 598 and ASME 16.34 requirements. When ordering a jacketed valve, there are a number of design concerns. Finding the ideal jacket configuration for your customer might be aided by the list below.

  1. Part Jacket with Standard Flange: In a partly jacketed ball valve, the original valve body is kept, and just the middle piece is encased. Only the center of the valve is immediately impacted by the temperature source, although the ends and flanges are also affected. This is a common approach to jacket valve designs. Half jackets can be an easy and affordable approach to maintain the flow of your customers’ products when complete jacketing is not required.
  2. Full Jacket with Standard Flange: Full jacket functionality is provided on a standard flange valve by the full jacket with a standard flange design. The jacket has blind threaded inserts that are welded into customized bolt holes in place of the type through holes over its entire length. The jacket is first welded to the valve’s flanges’ outside diameter, then to the valve body. Threaded studs are used to install this style of jacketed valve.
  3. Full Jacket with Oversized Flanges: A full port two-piece ball valve will need over-size flanges and two jackets—one on the valve body and one on the tailpiece—when completely jacketed, causing it to be extended end to end. Without covering the central valve body flanges, this design provides complete convergence. There are two or three exits on each jacket, depending on the valve type. Most valve designs allow for full jacketing. ​​

Application: Jacketed Ball Valve.

Several industrial operations, from the movement of bitumen and coal tar to the manufacturing of rubber goods, employ jacketed ball valves. They are also employed in the production of polymer goods, paints, and ink. These valves are frequently used in oil and gas processing plants, oil and petroleum refineries, petrochemical plants, pharmaceutical, and power sectors.
