ABSTRACT:
A power spray washing machine includes an enclosed wash cabinet positioned above a wash holding tank and a rinse holding tank. Openings are provided through a floor of the wash cabinet directly into the wash and rinse tanks, respectively. Vertical plug valves are associated with each opening to open and close the openings and control the flow of fluids therethrough. Each valve includes a first valve head moveable between a closed position in direct contact with and closing the opening and an open position out of contact with and uncovering the opening. The valve heads retain no fluid between the floor of the wash cabinet and the holding tanks when the valve head is in the closed position. By this arrangement, cross contamination of solutions between the wash and rinse holding tanks is minimized or eliminated.
