HEROSE provides safety around the world for the handling of technical gases, steams and liquids. With 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 of:
Valves for cryogenic liquefied industrial gases
When liquefied at cryogenic temperatures, the volume of industrial gases reduces by a factor of up to 600 and therefore enables economic solutions for transport and storage. Our know-how in the development and manufacture of cryogenic valves guarantees maximum process reliability in the handling of industrial gases.
Valves for cryogenic liquefied natural gas
Natural gas is liquefied at a temperature of -161°C and enables this versatile fuel to be supplied without depending on pipelines. We use our many years of experience in the field of industrial air gases to provided valves which are optimised for small-scale LNG applications.

In contrast to a standard ball valve on a changeover valve at least two safety valves are designed to protect the application (for example, a liquid gas tank) against impermissible overpressure.
A changeover valve has usually two outputs but one input only and serves to connect two safety valves with a pressure device. Changeover valves can be found in the area of air gases, vapours and in cryogenics at cryogenic liquefied gases such as Nitrogen. Cange-over valves are available in sizes from DN6 to DN50 and secure pressures up to 250 bar, at operating temperatures of -270°C to +400°C. The changeover valves are manufactured primarily in stainless steel but also in bronze and brass.
Valves for industrial applications
In order to prevent the uncontrolled rise in pressure in pressure vessels or pressurized pipelines, a safety valve is inserted. The safety valve is designed so that it opens at a given maximum pressure, thereby relieving the line or the container. Safety valves find their use in almost all areas of the pressure vessel and pipeline construction. In cryogenics as a spring-loaded safety valve for example.Sizes: DN8 to DN50
