EX1 Operating/Maintenance Manual

The AURA EX1 is a general purpose regulator designed to provide primary pressure control of gas or liquid for inlets up to 6000 psig where minor fluctuations in outlet pressure due to variable inlet pressures are accepted. AURA’s encapsulated seat design consolidates the numerous moving internal components of a standard regulator into one single piece, allowing for ease of maintenance and minimizing potential failure points. Protected by a 10-micron 360° filter, the encapsulated seat provides significantly more filtration of impurities than the standard pressed-in disk. The encapsulated seat also filters damaging particles from all inlet ports rather than just the pipeline port. Available with multiple seat materials and orifice sizes, the EX1’s capsule ensures optimum performance in any application.
AURA’s proprietary machining process yields surface finishes of 4-25 Ra designed to reduce corrosion. With its minimal internal volume, the EX1 also allows less gas to be used while purging. The AURA EX1 is assembled in a Class 100 clean room as a complete assembly with all gauges, fittings, and valves attached. The complete assembly is cleaned for oxygen service and is 100% helium leak checked. Additionally, the EX1 undergoes multiple flow and function tests to ensure the highest level of purity and durability.
Available with Dursan® LS inert and anti-corrosive technology that provides superior corrosive resistance versus exotic metals in highly acidic or caustic applications, the EX1 is the right choice for critical applications.
