ALL-IN-ONE COMPACT DESIGN

  • Ensure high-quality of the process thanks
    to a 5-in-1 design: shut off valve + integrated pressure regulator + flow selector+ filling port + gauge
  • Effcient solution for applications requiring additional pressure / flow regulating valve
  • Ergonomic design, all functions integrated for

SAFETY AND RELIABILITY

  • Protection of all the parts guarantees the work in better safe environment especially for mobile applications
  • Low-pressure components of the valve are protected for unintended high pressure
  • Re-closing device of the safety valve closes gas when pressure is below a threshold
  • Gas is tightly isolated during transport or storage thanks to the technology of manual shut-off valve
  • An optional safety relief device is a burst disk in line with a fusible metal. In case of a heat incident like a fire, the safety device empties the cylinder to avoid a burst of the cylinder

PRECISION

  • 7 fixed flow rates available (0,1 – 0,25 – 0,5 – 1,0 – 2,5 – 5,0 – 10,0 Nl/min N2)
  • Correct flow rate is guaranteed by flow selector
  • Stainless steel sintered filter prevents particles to flow to the end user system
