Refrigeration Overflow Valves

The AURA EXC is a compact, versatile regulator meticulously designed for precise and dependable pressure control of gases and liquids with inlet pressures up to 5500 psig. Its space-efficient structure makes it exceptionally suited for applications where minimising footprint and weight is essential. At the heart of the EXC lies AURA’s innovative encapsulated seat design, which integrates multiple moving parts into a single assembly. This design feature simplifies maintenance, reduces potential failure points, and significantly enhances long-term reliability. The seat benefits from a 10-micron, 360° filter, providing superior filtration compared to standard pressed-in disks. Unlike conventional designs that filter solely at the pipeline port, the EXC ensures comprehensive filtration across all inlet ports. With an extensive range of seat materials and orifice sizes, the EXC guarantees optimal performance for various global applications. Its ultra-compact, all-metal construction allows for seamless integration into systems or cabinets, while also ensuring durability and a long service life, even in harsh environments. Each AURA EXC unit is assembled in a Class 100 cleanroom as a complete system, which includes gauges, fittings, and valves. The assembly is meticulously cleaned for oxygen service, undergoes 100% helium leak testing, and is validated through multiple flow and function assessments to guarantee maximum purity, durability, and leak integrity. The AURA EXC represents a cost-effective solution for applications requiring compact, high-performance components without sacrificing reliability.
