1. A Activation of the drain valve occurs when the associated increase of oil pressure is sensed by the transducer, causing the signal from the controller to decrease.
2. B The transducer detects the presence of water in the processed oil.  It then sends a signal to the controller which initiates the opening of the drain valve.
3. C The water under centrifugal force developed within the bowl acts upon the underside of the valve, overcoming the opposing spring force, causing it to open.
4. D The water drain valve is used primarily when the bowl is flushed preceding a shut down period.  Its opening is the  result of a pre- programmed memory format.
