Diverter ball valve for the installation of for example two safety valves

in combination with bursting discs

for the protection of containers designed for the storage of cryogenic gases.

The requirements of the PED relating to redundant or diverse safety devices are fulfilled by this fitting in combination with safety valves of the 2400 / 2480 series.

On each side two additional connections for bursting discs are available. In case the safety valves need to be maintained or the bursting discs replaced, the side requiring maintenance can be shut off.


connection types

  • Internal pipe thread
  • Male thread
  • N2 for food/pharmaceutical applications
  • O2 for medical supply systems
  • CO2 for food / industrial applications
  • Ar for welding
  • Cooling plants

For systems for the storage of cryogenic liquefied gases such as LIN, LOX, LAr, CO2, LNG.

The ball valves are always manufactured free of oil and grease. For applications with oxygen (O2), they can be used up to a maximum of 40bar and 60°C.
