EX1 Series Single Stage Pressure Reducing Regulator
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.
