Features & Benefits :
      1. Heat Transfer Capability: The jacket surrounding the valve body enables the circulation of a heating or cooling medium, such as steam, hot water, or thermal oil. This feature allows for temperature control of the process fluid flowing through the valve.

      2. Maintaining Viscosity: In applications where the fluid needs to be maintained at a specific temperature to prevent solidification or maintain flow characteristics, jacketed plug valves are particularly useful. They ensure that the process fluid remains in a liquid state by providing consistent heating or cooling.

      3. Prevention of Fluid Solidification: Jacketed plug valves are commonly used in industries handling viscous fluids, such as bitumen, molten sulfur, chocolate, and polymers. By controlling the temperature of the valve body, they prevent the fluid from solidifying and blocking the valve or piping.

      4. Versatility: These valves are versatile and can be used in various industries including chemical processing, petrochemicals, food and beverage, pharmaceuticals, and more. They accommodate a wide range of process fluids and operating conditions.

      5. Corrosion Resistance: Jacketed plug valves are typically constructed from materials that offer excellent corrosion resistance, such as stainless steel or special alloys. This ensures durability and reliability in corrosive environments where the process fluid may be aggressive.

      6. Reliable Sealing: Like other plug valves, jacketed plug valves are designed to provide tight shutoff when closed, minimizing leakage and ensuring process integrity.

      7. Customizable Options: Manufacturers often offer customizable options for jacketed plug valves, including different sizes, materials of construction, heating/cooling medium connections, and pressure ratings to meet specific application requirements.

      In summary, jacketed plug valves are specialized valves designed to control the temperature of process fluids by circulating a heating or cooling medium around the valve body. They play a critical role in industries where maintaining fluid viscosity and preventing solidification are essential for efficient and safe operation.
