Application Scenarios<\/strong><\/h3>\n

The REGO<\/a> BR-1788 Series Regulators are engineered specifically for terminal pressure regulation in medical oxygen systems, while also delivering reliable performance across a diverse range of gases in both medical and industrial settings. Featuring a balanced valve seat design, these regulators are constructed with oxygen-compatible materials and equipped with tamper-resistant adjustment screws. Boasting exceptional flow capabilities, the 1\/2-inch and 1-inch models can achieve a maximum flow rate of 30,000 SCFH, while the 1\/4-inch model reaches up to 20,000 SCFH.<\/p>\n

Product Features<\/strong><\/h3>\n
    \n
  • Stable Downstream Pressure<\/strong>: Maintains consistent outlet pressure within the common inlet pressure range supplied by liquid oxygen storage tanks, ensuring uninterrupted gas delivery for critical applications.<\/li>\n
  • Precision Pressure Control<\/strong>: Large-area valve seats and diaphragms combine high flow capacity with minimal pressure drop, enabling accurate pressure regulation even under varying flow demands.<\/li>\n
  • Flexible Monitoring Options<\/strong>: Two 1\/4-inch FNPT plug-style gauge ports on each side of the valve body allow for easy installation of pressure monitoring devices, enhancing system visibility and safety.<\/li>\n
  • Versatile Mounting<\/strong>: Equipped with two bonnet drain\/vent ports, the regulators support multiple installation configurations to adapt to different spatial and operational requirements.<\/li>\n
  • Tamper-Resistant Design<\/strong>: A bonnet cap covers the adjustment screw, preventing unauthorized modifications and ensuring pressure settings remain consistent over time.<\/li>\n
  • Robust Pressure Ratings<\/strong>: With a maximum inlet pressure of 435 psig and four available pressure output ranges (A-D), the series caters to a wide spectrum of pressure control needs.<\/li>\n
  • Broad Temperature Compatibility<\/strong>: Operates reliably in extreme temperatures from -40\u00b0F to +165\u00b0F (-40\u00b0C to +74\u00b0C), making it suitable for harsh environmental conditions.<\/li>\n
  • Oxygen Service Compliance<\/strong>: Meets the cleaning requirements of CGA G-4.1 standard, ensuring safe use in oxygen-handling systems where contamination risks are critical.<\/li>\n
  • Quality Assurance<\/strong>: Undergoes 100% factory testing to guarantee performance, reliability, and adherence to strict quality standards.<\/li>\n<\/ul>\n

    Material Specifications<\/strong><\/h3>\n
      \n
    • Valve Body & Bonnet Vent<\/strong>: Forged brass, providing excellent durability and corrosion resistance.<\/li>\n
    • Diaphragm<\/strong>: Nitrile rubber lined with PTFE, combining flexibility with chemical inertness for long-lasting performance.<\/li>\n
    • Spring, Fasteners & Adjustment Screw<\/strong>: Stainless steel, ensuring strength and resistance to rust and corrosion.<\/li>\n
    • Other Valve Body Components<\/strong>: Brass, maintaining consistent material compatibility and structural integrity.<\/li>\n
    • Valve Seat Gasket & O-Rings<\/strong>: Standard Viton fluoroelastomer, offering superior resistance to high temperatures and aggressive gases.<\/li>\n<\/ul>\n

      Special Material Adaptations<\/strong><\/h3>\n

      For applications involving carbon dioxide or nitrous oxide, specify valve seat gaskets and O-rings made of EPDM material. This modification should be indicated by adding “E” to the end of the part number to ensure optimal compatibility and performance with these specific gases.<\/p>\n","protected":false},"excerpt":{"rendered":"
