Abstract
Disclosed is a rotary valve and rotary disk fluid dispensing system that sanitizes valve ports using UV radiation during non-use. Steam and ozinated water can also be used for stripping and disinfecting portions of the dispenser that can be accessed by the public. The system also uses detectors including hall detectors and a camera to inspect for blockage of valve ports, tampering or improper operation of the rotary valve disc.
