Abstract: An isolation valve for a fluid spray system includes an inlet module for receiving fluid from a main reservoir, an outlet module for providing fluid received from the inlet module to a sprayer, and an actuating module for driving the inlet module between a connected state and an isolated state. The inlet module is mechanically and fluidly connected to the outlet module in the connected state. The inlet module is spaced from the outlet module thereby generating an air gap and electrically isolating the inlet module from the outlet module in the isolated state. The outlet module includes a wash system that draws wash fluid from a wash reservoir as the inlet module transitions to the connected state and drives the wash fluid to clean a portion of the inlet module as the inlet module transitions from the connected state to the isolated state.

Abstract: An electrostatic spray gun comprises a gun barrel, a gun handle affixed to the gun barrel, and a spray tip assembly affixed to the gun barrel. The spray tip assembly comprises a tip assembly face, a tip disposed at the tip assembly face, an electrode extending perpendicularly from the tip assembly face, and a shield tower extending perpendicularly from the tip assembly face, and disposed cylindrically about the electrode.
