The AURA EX1 is a general purpose regulator designed toprovideprimarypressurecontrolofgasor liquidfor inlets up to 6000 psig whereminor fluctuations in outletpressureduetovariableinletpressuresareaccepted.AURA’sencapsulatedseatdesignconsolidatesthenumerousmovinginternal components of a standard regulator into one singlepiece, allowing for ease of maintenance and minimizingpotential failure points. Protected by a 10-micron 360° filter,theencapsulatedseatprovidessignificantlymorefiltrationofimpurities than the standard pressed-in disk.
