When tightening the lock ring "G" of the device shown in the illustration, two events are simultaneously accomplished. Which of the following statements represents these events? Illustration MO-0112

Correct Answer: Option C — When tightened, the lock ring allows for movement of the sliding piston and positions the sliding piston within the bowl bottom.

Tightening the bowl lock ring mechanically positions the sliding piston relative to the bowl bottom, establishing the proper hydraulic sealing configuration for continuous centrifugal separation and controlled periodic sludge discharge cycles.
