The AURA EXS is a high-precision single-stage regulator designed for sub-atmospheric control and low-flow positive pressure applications. Its innovative hybrid spring system, paired with an oversized dual-surface diaphragm, allows for precise pressure regulation ranging from 0 psia to 100 psig, delivering exceptional accuracy in both vacuum and positive pressure scenarios. Central to the EXS is AURA's unique encapsulated seat design, which combines multiple moving parts into a single assembly. This groundbreaking design simplifies maintenance, reduces potential failure points, and ensures long-lasting reliability. The regulator features a 10-micron, 360° filter that offers superior impurity removal, far surpassing that of standard pressed-in discs. Unlike conventional regulators that only filter at the pipeline port, the EXS provides comprehensive protection across all inlet ports. Each EXS regulator is meticulously assembled in a Class 100 cleanroom as a complete unit, with all gauges, valves, and fittings pre-installed. The assembly undergoes thorough cleaning for oxygen service, is 100% helium leak tested, and is subjected to rigorous flow and functional testing to meet the most demanding application requirements. For particularly aggressive environments, the EXS can be equipped with Dursan® LS inert coating technology, which ensures exceptional resistance to acidic and caustic media, often outperforming more exotic alloys. Combining precise control, robust construction, and advanced corrosion resistance, the AURA EXS stands out as the perfect choice for engineers seeking reliable solutions for sub-atmospheric and low-flow applications.

The Resideo DR300 Pressure Reducing Valve is designed to safeguard downstream installations from excessive supply pressure. Pressure regulators are essential when the capacity of directly controlled pressure reducing valves is inadequate. Their compact design makes them particularly suitable for installation in confined spaces, such as ducts. By incorporating a pressure regulator, you can prevent pressurisation damage and reduce water consumption. The set pressure remains constant, even amidst significant fluctuations in inlet pressure. Additionally, reducing the operating pressure while maintaining a consistent level minimises flow noise within the system.
