Distributor Vacuum Modulator Valve (DVMV)
Distributor Vacuum Modulator Valve (DVMV)
This valve has a calibration point of 8.7 inches of vacuum. Whenever manifold or ported vacuum is less than the calibration point, the DVMV switches to full manifold vacuum. Whenever the manifold or ported vacuum is greater than the calibration point, the DVMV switches to the highest vacuum, either manifold or ported.
