The VRV functions very much like a single stage pressure regulator, except this modified design allows the user to set the outlet pressure below atmospheric pressure. The VRV would be placed in between a vacuum line and a positive pressure source. When the vacuum source downstream draws pressure in the line below a desired set pressure, the VRV will crack open, allowing positive pressure to enter the system.
