Regulator Electricaly Heated, Single stage, Chrome-plated Brass, SS Diafragh, Series 308

Reference: 308-ABCD-CON-OP

The 308 Series regulators are specifically designed to prevent freeze-up problems associated with high flows of carbon dioxide and nitrous oxide. As Carbon Dioxide or Nitrous Oxide passes through a regulator seat, dry ice can form if the flow is too high, causing the regulator to freeze up.

Product description

The 308 Series regulators are specifically designed to prevent freeze-up problems associated with high flows of carbon dioxide and nitrous oxide. As Carbon Dioxide or Nitrous Oxide passes through a regulator seat, dry ice can form if the flow is too high, causing the regulator to freeze up.

Typical Applications:
  • Chemical storage blanketing
  • Anaerobic chambers
  • Inert gas purging
  • Atomic absorption oxidizer gas
  • Semiconductor reactor furnace
  • Inductively coupled plasma systems
  • pH control
Regulator Description:
  • 316L stainless steel membrane
  • Valve body chrome-plated brass
  • NEMA 4 Housing – For either indoor or outdoor use
  • Filter – sintered bronze 10 microns
  • Internal seal – PTFE
  • Maximum Input Pressure (3000 PSIG (210 BAR
  • Temperature range 35°C to 49°C
  • Heaters – 3 @ 50 watts each (110 or 220 VAC)
