Similar to the capabilities of RegO’s PB504 Series Pressure Build Regulator, the CBE504 unit can produce pressure-build speeds that are up to two times faster than competitive models. Additionally, because the CBE504 design combines the pressure-building and economiser functions in one unit, it saves space and simplifies installation in tight plumbing geometries, is 40% lighter than competitive models, and reduces leak points.

Notable features and benefits of the CBE504 Series Pressure Builder-Economizer Regulator include:

  • Maximum inlet pressure of 600 psig (41.4 barg) and a set pressure range of 25 /- 550 psig (1.7 to 37.9 barg).
  • Cryogenic temperature rating from -196°C – 65°C (-320°F – 150°F).
  • Designed and suitable for use in various cryogenic industrial gases, including nitro-gen, oxygen, argon, carbon dioxide (CO2) and LNG. For optimum performance with CO2 and nitrous oxide, use in gas phase.
  • Economiser setpoint linked to pressure builder setpoint, which helps ensure correct adjustment.
  • Lateral economiser port with 1.7 times larger flow area than competitive models for faster response time and reduced product loss.
  • Economiser seal design tied strictly to the PB Outlet function to prevent pressure runaways, further reducing potential for product loss.
  • Internal economiser-check function reduces potential for product loss by preventing reverse flow.
  • Calibrated pressure adjustment on bonnet cap allows for faster, more accurate pressure-set adjustments.
  • One-piece PTFE poppet seat provides better guidance for improved seating, which helps eliminate leak paths at cryogenic temperatures.
  • Monel screens on pressure builder help prevent accumulation of debris in the regulator seat, resulting in longer seat and seal life.
  • Copper gasket provides superior seal under cryogenic temperatures to help prevent leakage.
  • Unit can be mounted vertically with economiser port in sideways position or horizontally with economiser port in upward position.
  • PED (SEP) certified and CRN registered (#0C21549.25).
  • 10-year RegO product warranty.
