1. A chemical dispenser for a chemical dispensing system, comprising:
an input selector valve having opened and closed positions and configured to be coupled to a diluent source;
a diverter valve coupled to the input selector valve; and
a plurality of eductors coupled to the diverter valve,
wherein the diverter valve comprises:
a valve head having a diluent port and one or more pressure relief ports configured to equalize diluent pressure across the valve head;
a valve seat having a plurality of eductor ports, each eductor port of the plurality of eductor ports in communication with a respective one of the plurality of eductors; and
a drive mechanism configured to move the valve head relative to the valve seat so that diluent may flow through each of the plurality of eductors when the input selector valve is in an opened position and the diluent port of the valve seat is in communication with the eductor port of the plurality of eductor ports corresponding to the each of the plurality of eductors.
