Diverter ball valve made of gunmetal with threaded connections

As already implemented with the stainless steel series 2700, the gunmetal diverter ball valve 2780 possesses a flow geometry with very low pressure loss. The safe functionality of the safety valves mounted on the diverter ball valve is therefore better ensured. Additionally, opposite to the vertically mounted safety valves, there are also connections for bursting discs available. Due to the consistent cleaning of all component parts, the gunmetal diverter ball valve is also optimally suited for use in systems using oxygen.

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 fulfi lled by this fi tting in combination with safety valves of the 2400 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.

  • For the storage of cryogenic liquifi ed gases, such as LIN, LOX, LAr, CO2, LNG.
  • N2 in pharmaceutical / foodstuffs applications
  • O2 for medical supply equipment
  • CO2 for foodstuffs/ industrial applications
  • LAr for welding
  • Cooling plants
