Critical processes demand precise controls. AURA regulators provide
primary and secondary pressure control of liquids and gases ranging
from high pressure to sub-atmospheric levels in the most challenging
analytical applications. Manufactured and assembled in the United
States, each device is backed by an exclusive Lifetime Warranty and
decades of industry experience. Innovative designs, superior performance
and robust technology define the AURA advantage.

The AURA EX1 provides primary pressure control of gases and liquids where minor
fluctuations in outlet pressure due to variable inlet pressure are accepted. Available
with multiple porting options, peripherals and end connections, the EX1 is a reliable
general purpose regulator designed to fulfill a wide variety of applications such as
instrument panels, skid-mounted systems and line pressure control.

The AURA EX2 is designed to provide steady and precise outlet pressure control of
gases and liquids regardless of changes in inlet pressure. The EX2’s dual surface
diaphragm provides sensitive pressure control and the encapsulated seat design
eliminates impurities. The EX2 is ideal for systems requiring constant outlet pressure
such as instrument calibration, compressed gas cylinders and distribution systems.

The AURA EXB provides adjustable relief of excess pressure in closed loop systems
caused by spikes in inlet pressure. Unlike standard relief devices that only provide
open/close functions, the EXB allows the end user to throttle excess pressure. The
EXB is a versatile solution for applications such as analytical instrumentation and
processing skids.

The AURA EXH supplies principle pressure control of gases and liquids in closed loop
systems requiring delivery pressures as high as 4500 psig. The standard self-venting
feature allows gas downstream to be safely relieved as the desired outlet pressure is
decreased. The EXH is a reliable and flexible fit in applications such as test benches,
process line surge protection and aerospace systems.

The AURA EXV provides steady and reliable heat to vaporize and maintain gas phase
of samples for analysis. The proprietary labyrinth-style flow path maximizes the heated
surface area to prevent samples from condensing. Available in both electronically and
steam heated designs with numerous temperature, wattage, and voltage options, the
EXV is a versatile solution for applications such as hydrocarbon analysis, natural gas
sampling systems and fluid analysis.
