1. An electrostatic spray system for spraying electrostatically charged liquids comprising a high voltage section including a container for supplying conductive liquid, a source of a high voltage for electrostatically charging the conductive liquid, a valve manifold having at least one electrically operated valve thereon coupled to the container for controlling dispensing of electrostatically charged liquid under pressure at a location remote from the high voltage section, a low voltage support including a source of liquid for the container and a control for controlling liquid flow from the low voltage support to the high voltage section, wherein the improvement comprises a radio frequency transmitter on the low voltage support, and a radio frequency receiver on the high voltage section, said radio frequency receiver being coupled to operate the at least one valve and the radio frequency transmitter being on the low voltage support under operator control for transmitting selecting frequencies to the radio frequency receiver for operating the at least one valve to control dispensing of electrostatically charged liquid.
