A pressure-responsive control valve is especially useful to control aspiration of fluids from a patient during a surgical procedure. The control valve includes features which control the aspiration suction level communicated to the patient, which prevent reverse flow positive pressure from communicating to the patient, which safely vents such a reverse flow positive pressure in the event it reaches a level jeopardizing the integrity of the valve or plumbing fixtures, and which prevents aspirated fluids from weeping from the valve into the surgical environment in the event that a positive pressure communicates to the inlet of the control valve.
