RegO Products Introduces New CBE504 Series Pressure Builder-Economizer Regulator

Lighter weight model and wider pressure range optimize cryogenic-storage vessels

DOWNERS GROVE, Ill., Sept. 6, 2023 /PRNewswire/ -- RegO Products, part of OPW Clean Energy Solutions and Dover (NYSE: DOV), announced the launch of its new CBE504 Series Half-Inch Pressure Builder-Economizer Regulator, which enables cryogenic vessels to achieve and maintain proper pressures with minimal risk of product loss.

The new CBE504 unit is 40% lighter and produces pressure-build speeds that are up to two times faster than competitive models. Combining the pressure-building and economizer functions into one unit saves space and simplifies installation in tight plumbing situations.

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 to 550 psig (1.7 to 37.9 barg);
  • Cryogenic temperature rating from -320ºF to 150ºF (-196ºC to 65ºC);
  • Designed for use in various cryogenic industrial gases, including nitrogen, oxygen, argon, CO2 and LNG*;
  • Economizer setpoint linked to pressure builder setpoint, which helps ensure correct adjustment;
  • Lateral economizer port with 1.7 times larger flow area than competitive models supports faster response time and reduced product loss;
  • Economizer seal design tied strictly to the PB Outlet function mitigates against pressure runaways, further reducing potential for product loss;
  • Internal economizer-check function reduces potential for product loss by helping prevent 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 or horizontally;
  • PED (SEP) certified and CRN registered (#0C21549.25); and
  • 10-year RegO product warranty.
