Cryogenic Line Regulators

The BR-1780 Series of regulators are designed for final line pressure regulation on medical oxygen systems. They are equally suitable for a variety of gases in medical or industrial applications. The BR-1780 Series Regulators have a balanced seat, are constructed with oxygen compatible materials, and offer a tamper resistant adjustment screw cap. Flow performance is impressive as well offering up to 30,000 SCFH for the 3/4” and 1” model and up to 20,000 SCFH for the 1/2” model. For Carbon Dioxide and Nitrous Oxide Service: Specify EPDM material for seat disc and 0-Rings, add “E” to end of part number.

Features

• Maintains a steady downstream pressure across a range of inlet pressure commonly provided by a cryogenic bulk tank.
• Large seat and diaphragm areas provide high capacity with sensitive control of delivery pressure with low falloff.
• Two ¼” FNPT delivery pressure gauge ports are located (plugged) on each side of the valve.
• Two bonnet drain/vent holes to allow for different mounting orientation.
• Bonnet cap covering adjusting screw for tamper protection.
• Maximum inlet pressure is 435 psig.
• Available in four delivery pressure ranges.
• Temperature range: -40° F to +165° F.
• Cleaned per CGA G-4.1 for oxygen service.
• 100% Factory Tested
  
  

The 1780 Series of regulators are designed for final line pressure regulation on gas distribution systems. They are suitable for a variety of gases in medical or industrial applications. The 1780 Series Regulators have a balanced seat, are constructed with oxygen compatible materials, and have the same valve design, brass body, and internal parts as the premium BR-1780 Series. Flow performance is likewise equal to the BR-1780 Series. For Carbon Dioxide or Nitrous Oxide service: Specify EPDM material for seat disc and O-rings, add “E” to end of part number.
