Description: The VRD8 is a manifold mount configuration of the VRD single stage vacuum regulator. When placed in line after a vacuum source, it will control vacuum from 0 psig (29.5 in-Hg) down to -12.7 psig (4 in-Hg).
Approximate Weight: 25g in brass and stainless. Weight will vary slightly, depending on configuration. Selecting the 2 inch. high resolution cap option adds approximately 50-60g to total weight.
Materials: Brass or 303 stainless steel body. 18-8 stainless steel springs in flow path.
Porting: 10-32 external threaded inlet port. 0.050” (1.27mm) diameter outlet ports. Vacuum source should be connected to the inlet port.
This is a Non-Relieving regulator. You can increase the vacuum setting (greater vacuum) by turning the knob. You can not decrease the vacuum setting (less vacuum) from the initial setting unless you vent the downstream line to atmosphere.
