Jacketed ball valves are designed to offer good performance and longevity even in harsh environments. They offer excellent insulation, which is an essential factor in many thermal transfer applications. These valves are best suited for chemical processing, oil and gas production, and power generation, where leak-tightness and reliability are critical factors. In this article, we will explore the different types of jacketed ball valves and their specific uses.

Types of Jacketed Ball Valve:

Standard Jacketed Ball Valves – 

Standard jacketed ball valves have a full jacketed body and are designed to handle critical applications with ease. This type of valve is fitted with flange end connections, making it easy to install and use. They feature a single-piece body design that ensures high integrity, and their robust construction offers excellent sealing performance. Standard jacketed ball valves are best suited for applications that require low to moderate temperatures. Typical applications include chemical plants, oil and gas refineries, and storage tank farms.

Partial Jacketed Ball Valves –

Partial jacketed ball valves feature a split-body design, with only the seat, ball, and stem receiving a jacketed construction. These valves are designed for applications that require efficient heat transfer while minimizing the valve’s cost. Their unique design provides an optimal balance between price and performance. Partial jacketed ball valves are best suited for applications that require moderate temperatures and reduced cost. Typical applications include food processing, pharmaceutical production, and water treatment.

Cryogenic Jacketed Ball Valves:

Cryogenic jacketed ball valves are designed to handle extremely low-temperature applications, such as liquefied natural gas (LNG) or liquid nitrogen. They feature valve bodies and extension bonnets, which are cryogenically treated to handle extreme temperatures. These valves are fitted with materials such as Invar or stainless steel to reduce thermal contraction. Cryogenic jacketed ball valves are best suited for applications that require extremely low temperatures. Typical applications include the oil and gas industry, petrochemical plants, and air separation units.

Steam Jacketed Ball Valves:

Steam jacketed ball valves are designed to handle high-temperature liquids or gases. These valves are fitted with an insulating jacket surrounding the valve body, providing efficient thermal transfer. Steam jacketed ball valves are commonly used in power generation and chemical processing industries. Steam-jacketed ball valves are best suited for applications that require high temperatures. Typical applications include steam production, power generation, and chemical processing.

Fully Welded Jacketed Ball Valves:

Fully welded jacketed ball valves are designed for applications where leak-tightness is critical. These valves feature a fully welded construction that eliminates the need for flange connections, resulting in a more compact design. They are commonly used in pipeline applications where high integrity is needed. Fully welded jacketed ball valves are best suited for pipeline and transportation applications. Typical applications include the oil and gas industry, petrochemical plants, and chemical processing.

Conclusion:

Jacketed ball valves are an essential component in many harsh environment applications, offering excellent insulation and superior leak-tightness. By understanding the different types of jacketed ball valves available, their construction, and their uses, you can make an informed decision when choosing the right valve for your application. Whether you need a standard jacketed ball valve, a partially jacketed valve, a cryogenic jacketed valve, a steam jacketed valve, or a fully welded valve, make sure you choose a reliable and trusted supplier that can provide you with the highest quality valves.
