About us

HEROSE provides safety around the world for the handling of technical gases, steams and liquids.

With more than 140 years experience in the development, manufacture and sale of valves with a high level of innovation and modern production with certified quality management, our company is one of the world's leading manufacturers and suppliers for fittings and safety valves for cryogenic technology, valves for small-scale LNG applications, safety valves for general industrial applications and special fittings for oil-immersed transformers.

HEROSE valves for oil-immersed transformers have proven themselves for decades in heavy-duty use for electricity generation and distribution – worldwide.

Because of this, many well-known transformer manufacturers rely on the legendary HEROSE quality, which is guaranteed by careful selection of materials and continuous quality controls.

Products and services

On our stand we'll present the following products:

  • Gate valves (incl. a version with “Guillemin“-outlet)

    HEROSE gate valves are used to regulate the oil circulation in transformers. There is a wide variety of versions, designed for use at extreme temperatures down to -60° C, as well as for offshore applications.

  • Ball valves

    HEROSE ball valves are ideally suitable for handling neutral gases and liquids, mineral oil products and alkalis, as well as corrosive liquids and gases.

  • Outlet valves

    HEROSE outlet valves made from bronze and seawater-resistant bronze are used on oil-immersed transformers for the safe removal of oil samples for quality checks.

  • Three-way plug cock

    HEROSE three-way plug cocks provide a defined oil flow and therefore the controlled dissipation of heat within oil-immersed transformers.

    We are pleased to welcome you on the desired exhibition and would be very glad to present our new technologies, products and services of our ENERGY business field to you.

15230 / 15235 - ball valves

15230 / 15235 - ball valves

Due to the increasing price pressure in the market HEROSE has taken a cheaper alternative to ball valves in the program for the business field ENERGY. With immediate effect, the new versions of ball valves made ​​of cast steel (type 15230) and stainless steel (Type 15235) are available.
After successful completion of long-term tests, the new types will complement the previously available ball valves of type 15210 and 15215.

15225 - ball valves

In the context of extension the products range of the ENERGY business field, we have supplemented the ball valves by an additional compact version. From now on, new versions of the ball valves are available in stainless steel (type 15225). After successfully completed tests, this new design will now complement the 15210, 15215, 15230 and 15235 ball valves. The type 15225 is more compact and lightweight and an attractive alternative to the existing types also in price.
