Description: 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.
- Vacuum Control Range: The VRV will control vacuum from 0 psig (29.5 in-Hg) down to -12.7 psig (4 in-Hg).
- Approximate Weight: 25g in 303 stainless steel. Weight will vary slightly, depending on configuration. Selecting the 2 inch. high resolution cap option adds approximately 50-60g to total weight.
- Porting: 10-32 internal threaded inlet and outlet port. Positive pressure source should be connected to the inlet (deeper) port.
