Jacketed Plug Valve

South American Valve is the top most jacketed plug valve supplier in Mexico. A jacketed plug valve is a type of plug valve that incorporates a jacket or cavity surrounding the valve body to allow for temperature regulation of the process fluid. It is commonly used in applications where the fluid passing through the valve requires heating or cooling to maintain its viscosity or prevent freezing. The body of a jacketed plug valve is typically made of cast or forged steel. It houses the internal components and provides structural support. The body has an additional cavity or jacket surrounding it to accommodate the temperature control medium.

South American Valve is the top most jacketed plug valve supplier in Mexico. Jacketed plug valves are commonly used in industries such as oil and gas, chemical processing, food processing, and pharmaceuticals. They are suitable for applications involving temperature-sensitive fluids, where maintaining a specific temperature range is crucial for process efficiency, product quality, or safety. The jacketed design allows for precise temperature control and prevents the process fluid from solidifying or experiencing undesirable temperature variations.

  • Chemical Processing: Jacketed plug valves are widely used in chemical processing plants for handling various corrosive fluids, chemicals, and hazardous substances. They help regulate the temperature of the process fluid to prevent solidification, maintain fluid viscosity, and ensure optimal performance of the valve in critical chemical processes.
  • Petrochemical Industry: In the petrochemical industry, jacketed plug valves are employed in processes involving petroleum derivatives, gases, and other hydrocarbons. They are used to control the flow of hot oils, bitumen, asphalt, and other high-temperature fluids, ensuring consistent temperature control and preventing material solidification or excessive viscosity.
  • Oil and Gas: Jacketed plug valves are utilized in the oil and gas industry for applications such as refineries, pipelines, and storage terminals. They help regulate the temperature of crude oil, natural gas, and other hydrocarbons to prevent solidification or excessive viscosity, ensuring smooth flow and efficient operation.
  • Pharmaceutical Industry: Jacketed plug valves are employed in pharmaceutical manufacturing processes where precise temperature control is crucial. They are used to regulate the flow of pharmaceutical ingredients, solvents, and other critical fluids, ensuring compliance with strict temperature requirements and maintaining product integrity.
  • Cryogenic Applications: Jacketed plug valves are utilized in cryogenic applications where extremely low temperatures are involved. They are employed in industries such as LNG (liquefied natural gas) terminals, cryogenic storage facilities, and air separation units to handle and control the flow of cryogenic liquids, such as liquid nitrogen or liquid oxygen, while preventing freezing or solidification.
  • Adhesives and Polymers: In industries that involve the handling of adhesives, sealants, and polymers, jacketed plug valves are utilized to regulate the temperature of these viscous fluids. They help prevent material buildup, maintain fluid flowability, and ensure consistent processing in adhesive and polymer manufacturing processes.


  • Precise Temperature Control: The primary benefit of jacketed plug valves is their ability to provide precise temperature control of the process fluid. The jacket surrounding the valve body or plug allows for the circulation of a heating or cooling medium, maintaining the desired temperature range of the fluid. This precise temperature control is crucial in industries where temperature-sensitive processes or materials are involved.
  • Prevents Fluid Solidification or Crystallization: Jacketed plug valves help prevent the solidification or crystallization of fluids that can occur due to low temperatures. By providing a continuous circulation of a heating medium, they ensure that the process fluid remains at a temperature above its solidification or crystallization point. This is particularly important in industries handling viscous or sticky fluids that can solidify or form deposits at lower temperatures.
  • Reduced Maintenance and Downtime: Jacketed plug valves help reduce maintenance and downtime associated with temperature-related issues. By maintaining the process fluid temperature within the required range, they minimize the risk of clogging, solidification, or other problems that can lead to valve malfunction or process disruptions. This results in improved operational efficiency and reduced downtime for maintenance and repairs.
  • Corrosion Protection: In certain applications where the process fluid is corrosive or chemically reactive, the jacket surrounding the valve body or plug can act as a protective barrier. By circulating a compatible medium through the jacket, jacketed plug valves provide an additional layer of protection against corrosion, extending the valve’s service life and reducing the risk of leaks or failures.
  • Versatility and Adaptability: Jacketed plug valves are versatile and can handle a wide range of fluids, including liquids, gases, slurries, and corrosive substances. They can be customized to suit specific process requirements, such as the type of jacketing, material compatibility, and temperature range. This adaptability makes them suitable for use in diverse industries and applications.
  • Enhanced Safety and Environmental Compliance: Jacketed plug valves help ensure safety and environmental compliance by preventing leaks, spills, or emissions associated with fluid solidification, crystallization, or extreme temperatures. The tight shut-off and temperature control provided by jacketed plug valves minimize the risk of process disruptions, product contamination, or environmental hazards.
  • Reliable Operation: Jacketed plug valves are designed for reliable and efficient operation. They offer tight shut-off capabilities, precise flow control, and low maintenance requirements. The jacketing feature helps maintain consistent valve performance by mitigating temperature-related issues that could affect valve operation or compromise system integrity.
