Valve box and pigtails

Safe connection from the cylinder to the gas station

Valve-boxes are essential components for the creation of supply manifolds for the high pressure gas station. This device, combined with a pigtail, is used to connect the cylinder to the gas station. Pigtails are the final connectors of the high pressure gas station. They supply the gas network by connecting the valve-boxes with the cylinders at high pressure.

The valve-box


  • Choice of confi guration, 1 or 2 cylinders connected
  • Kit assembly, possibility of connecting several valve-boxes
  • Adaptable to a main or backup manifold

High level of safety

  • Automatic regulation of the manifold pressure thanks to its controlled pressure reduction system
  • No risk of pigtail fl apping when changing the cylinders thanks to its non return valve
  • Limited risk of adiabatic compression thanks to its “zero plastic” design


  • Adapts perfectly to all medical gases
  • Equalisation of manifold pressure, for a real visualisation of the pressure on the gauges
  • Facilitated leak detection; the measured pressure matches the overall pressure of the manifold


The pigtail

Simplified use

  • Simply tighten/loosen by hand to replace cylinders
  • Modifiable mounting direction, from the right or from the left
  • Compact

Guaranteed safety

  • Connected by hand, impossible to disconnect under pressure
  • Pigtail sealed with the valve-box


  • Unbreakable connection with induction brazing
  • Longer life (made of stainless steel)
  • No damage to the connections on the cylinder side, thanks to tool-free connection



  • Controlling high pressure
  • Adapts perfectly to all medical gases
  • Ideal configuration, kit assembly
  • Pressure equalisation and self-regulation



  • Essential to the Danube gas station
  • Safer supply to the network
  • Tightened/loosened by hand, simple and no risk of damaging the connectors
  • Greater modularity thanks to connection from the left or from the right
