Equilibar® Very Low Pressure Regulator

The Equilibar® Precision Back Pressure Regulator offers unparalleled performance in the very-low pressure region.  The device is capable of matching process gas or liquid pressures to that of a pilot reference signal to within 1mm water column. 

This extraordinary precision makes the Equilibar® uniquely qualified for high precision / low-pressure applications in the bio-medical and research fields, among others. 

The EB2SC3 is available in special -LP trim for low pressure applications. See product details for the EB2SC3.

OverPressure is defined as the difference between the process pressure and the reference pilot signal pressure.

In one medical research application, an IV water bag is used to supply a precision reference signal of several millimeters of water.  The Equilibar®  controls the pressure of body cavity gases to the reference signal with unmatched accuracy. Electro-pneumatic regulators can be used for automated applications.

To achieve this superior sensitivity, a standard body of the Equilibar is outfitted with a highly sensitive diaphragm suitable for the application.  Materials available include PTFE, polyolefin, Buna N, EPDM, and others.   Standard bodies come in SS316L, with PTFE and polypropylene also available.
