How It Works
The RV-19 is a dome-loaded pressure regulator with pilot operation. This means gas or air is fed into the top (dome) area of the regulator to provide the pressure setpoint in a 1:1 ratio. The pressure of the gas in the dome is set by a separate mechanical or electro-pneumatic device such as the RVP mechanical pilot regulator. This pilot pressure forces the flexible diaphragm down onto a plate of orifices. A rise in inlet pressure lifts the diaphragm up to allow excess pressure to be relieved through the outlet orifices. Similarly, a loss of pressure at the inlet causes the diaphragm to be pushed closer to the orifices, restricting flow and rebuilding pressure upstream.

How It Works
*Equilibar control valves have historically not been for use in commercial ventilator systems. In connection with the COVID-19 pandemic, Equilibar has retrofitted its valves for potential use in connection with medical ventilator systems. While our valves are not approved for any medical use by the FDA or any other governmental agency, Equilibar plans to produce these valves in volume and offer the valves, with affordability in mind to the extent possible, to businesses or governments who are actively seeking or agree to seek qualifying approval for the sale or distribution of integrated systems for use within a medical setting from the U.S. Food & Drug Administration (“FDA”) or other similar governing agency in local jurisdiction. Your agreement to any terms of sale with respect to our valves asserts that you are a technically competent entity capable of evaluating system risk and seeking Emergency Use Authorization from the FDA or other similar governing agency in local jurisdiction.
All rights to use our valves shall be effective from the date we provide the valves to you until such time as we notify you that your use must end which reasons may include, without limitation, end of the existing pandemic or recalls for safety reasons.
Use of our valves and/or drawings shall be solely as provided for in a legal agreement with you which will include, in part that any sale is (i) not and does not represent medical or legal advice by Equilibar, (ii) is not approved or available as alternative to an FDA approved ventilator and (ii) “AS IS, WHERE IS, AND WITH ALL FAULTS’’. If you do not agree with any of the foregoing do not purchase or use any of our valves for use other than as originally intended (i.e. commercial ventilator systems).
