One product – many possibilities

FullX - a Top-Entry valve for special requirements.
Our valve can be used in a variety of applications offering many advantages. The HEROSE FullX can be individually planned and optimally installed in a vacuum-insulated system. It protects against unwanted rapid evaporation. The product is characterized by high internal and external tightness and is absolutely reliable with a long service life. The Top-Entry function enables quick and cost-effective maintenance that are carried out without vacuum losses.

Our extensions, your advantages

  • Cast body – more variance in the choice of housing
  • Purge port available in all nominal sizes and housings – with the purge port less media loss is faced when purging the top work during the cooling process
  • Firesafe design
  • TPED / TPER approval
  • New collar with many advantages
    • Thermally optimized
    • Extended heat input

Areas of application
The FullX iperfectly suits for vacuum-insulated pipes, for example in hydrogen liquefaction, air separation and cold box systems. It is therefore also suitable for the use in pressure vessels for helium, hydrogen, LNG and oxygen. Refuelling systems in the aerospace industry and in cryostats are the ideal areas of applications for our valve.
