REGO BR-1788 Series Heavy Duty Brass Final Line Pressure Regulator ‌Cryogenic Industrial Gas Pressure Reducing Valve‌

Application Scenarios

The REGO 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.

Product Features

• Stable Downstream Pressure: Maintains consistent outlet pressure within the common inlet pressure range supplied by liquid oxygen storage tanks, ensuring uninterrupted gas delivery for critical applications.
• Precision Pressure Control: Large-area valve seats and diaphragms combine high flow capacity with minimal pressure drop, enabling accurate pressure regulation even under varying flow demands.
• Flexible Monitoring Options: 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.
• Versatile Mounting: Equipped with two bonnet drain/vent ports, the regulators support multiple installation configurations to adapt to different spatial and operational requirements.
• Tamper-Resistant Design: A bonnet cap covers the adjustment screw, preventing unauthorized modifications and ensuring pressure settings remain consistent over time.
• Robust Pressure Ratings: 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.
• Broad Temperature Compatibility: Operates reliably in extreme temperatures from -40°F to +165°F (-40°C to +74°C), making it suitable for harsh environmental conditions.
• Oxygen Service Compliance: Meets the cleaning requirements of CGA G-4.1 standard, ensuring safe use in oxygen-handling systems where contamination risks are critical.
• Quality Assurance: Undergoes 100% factory testing to guarantee performance, reliability, and adherence to strict quality standards.

Material Specifications

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

Special Material Adaptations

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.
