SJM JFK (Customer) asked a question.
Will the Nitra DVP-2C valves work for less than 1"w.c. vacuum?
- K Price (Customer)
The Nitra DVP-2C valves do not include "vacuum" in their pressure range specs. The pressure range is listed as "0-200 psi". This would be gauge pressure, so 0 psi would be ambient pressure. Other valves do include vacuum in their pressure range specs. For example, Nitra CMV valves' pressure range is listed as "vacuum-145 psi". Curious that they do not specify the actual vacuum rating, but only use the vague term "vacuum"?

USUALLY, a Pilot Operated Valve will work in the Low Vacuum Ranges.. The Valve is shifted by the Pilot Air, usually min of 30 to 60 PSI separate Air Source.
LIKELY the Seals in the Valve Body might leak as they are Being 'Pulled' rather than 'Pushed' in the Design..
HOWEVER operating 'Things' out of the Design Spec is always risky, even it it works for now..
Your Millage Might Vary..

Those are direct acting valves (not solenoid/pilot assist) so they will support a vacuum, but there are no details about how strong of a vacuum.

Thank you very much ADC... That is what I thought but didn't want to rely on an assumption.
