Abstract
A selector valve assembly for use in conjunction with an eductor dispensing system which reduces the incidence of product carry-over when the valve is moved from one position to another. The selector valve assembly also reduces the incidence of improper dispensing. In a preferred manner, the selector valve assembly has a single valve member and accommodates four product inlet lines for selectively passing chemical concentrate to two eductors. The selector valve assembly is composed of a minimum of ports, thereby reducing maintenance and cost.
