Detailed performance curves are provided for the EVR-3 3/8″ regulator, though the same flat-line performance can be expected for other models when properly sized.
Stability across widely varying flow rates — Four orders of magnitude!
This chart shows flat line pressure stability across an incredible 4 orders of flow rate magnitude. Competitive data, where available, is typically published across a narrow range of flow.
Why is ultra low flow performance important? If your flow rate falls below the minimum for the regulator, then excessive vacuum can result.
Stability across varying Supply Pressure
This chart at right shows the excellent vacuum stability as the vacuum pump supply pressure varies widely.
Selecting the right size
This chart shows the projected vacuum performance at various regulator body sizes. If you don’t have a prefered piping size in mind, select the smallest regulator that gives the precision that your application requires.
