1. A fluid application system comprising:
a manifold defining an internal passageway; and
a plurality of nozzle assemblies connected in fluid communication with the internal passageway, wherein each nozzle assembly of the plurality of nozzle assemblies comprises:
a body defining a fluid passage;
an inlet connected to the manifold for receiving fluid flow into the fluid passage;
a spray outlet for discharging fluid from the fluid passage;
an electrically actuated valve fluidly connected between the inlet and the spray outlet and configured to control fluid flow through the fluid passage; and
a pressure dampener connected in fluid communication with the fluid passage between the inlet and the spray outlet and configured to dampen fluctuations in fluid pressure within the fluid passage.
