Advantages for our customers

Process reliability

Heating jackets ensure that media such as oils, greases or resins do not cool down and solidify. This reduces downtimes and increases operational safety.  

Hazardous substance protection

Leakage jackets are essential for applications with toxic or environmentally hazardous media. They prevent uncontrolled leaks and protect personnel and systems.

Customized production

We adapt heating and leakage jackets precisely to your fittings and installation situation. Special sizes and special connections are possible at any time.

Testing & Quality

Each unit is tested in accordance with the standard, including pressure and leak tests. Documentation for your QA is a matter of course.

Made in Germany

Uniform quality standards

Technical details – Heating jackets &
Leakage jackets

Our heating and leakage jackets are manufactured individually according to your requirements and meet the highest quality standards.

Fitting types

Suitable for a wide range of industrial valves such as ball valves, valves, filters and strainers. Special solutions for special fittings are also possible.

Executions

We offer single jackets for standard applications as well as double jacket designs for particularly demanding processes where even heat distribution or additional safety is required.

Heating media

Depending on the process requirements, heating takes place via steam, water or thermal oil. We can advise you on the selection of the optimum heating medium for your application.

Materials

We use high-quality stainless steel as standard, which is characterized by its corrosion resistance and durability. Special materials are also available for aggressive media or special requirements.

Temperature ranges

Our heating jackets are designed for operating temperatures up to 200 °C. Higher temperatures can be realized on request.

Connections

Flexible connection options such as threaded or flanged connections as well as individual special solutions ensure perfect integration into your system.

Heating jackets for fittings & filters – Efficient temperature control in the process


Heating jackets ensure the reliable temperature control of fittings, filters and containers. They prevent media from cooling down or solidifying, thus ensuring smooth system operation – even in demanding processes.


The design and customization is carried out individually according to customer wishes and process requirements. As a valve manufacturer, we supply heating jackets as individual components or as a complete system – including modifications and suitable valves on request.

Heating jacket for automated valves

Customized heating jackets for automated valves.

  • For 2-way and 3-way ball valves, 2-part and 3-part versions with actuator
  • Block ball valves and compact ball valves with pneumatic or electric actuator
  • Globe valves for demanding applications

Examples of equipment

  • Heatable ball valves with mechanical limit switches and visual position indicator (DVC type 5320)
  • With pneumatic quarter-turn actuator Air Torque, type Edition 2000
  • Equipped with magnetic switch according to NAMUR hole pattern (DVC type 5226)

Heating jacket / double jacket for ball valves

We manufacture heating jackets for all common ball valve designs, including:

  • 2-way and 3-way ball valves for standard and special applications
  • 2-part and 3-part flanged ball valves and variants for butt weld ends
  • Block ball valves and compact ball valves that require a space-saving solution
  • Plug valves with welded stainless steel housing, ideal for robust industrial applications

Our heating jackets are available as single or double jackets. The double jacket ensures particularly even heat distribution and is the first choice for demanding processes.

Heating jacket for valves

Customized heating jackets and leakage jackets for various valve types – exactly according to your requirements:

FAQs

What are heating jackets used for?

Heating jackets prevent viscous media such as oils, greases or resins from cooling and solidifying in fittings and pipes. They ensure a continuous process flow and prevent production downtimes.

A heating jacket is used to maintain the temperature and heat fittings. A leakage jacket, on the other hand, protects against the escape of hazardous media and increases safety when handling hazardous substances.

Our heating jackets can be manufactured for ball valves, valves, filters and strainers. Special solutions for other valve types are also possible.

Depending on the process requirements, heating jackets can be operated with steam, water or oil. We can advise you on the selection of the right heating medium.

Yes, we manufacture heating and leakage jackets exactly according to your project specifications. Special sizes, special connections and individual materials can be implemented at any time.
