ABSTRACT:
A spray gun for applying an electroless plating solution includes a handle, a trigger connected to the handle, a nozzle assembly connected to the handle, a first fluid passage, a second fluid passage, a switch, and a valve assembly. The nozzle assembly includes a first fluid path having a first outlet and a second fluid path having a second outlet. The first fluid passage is in communication with the first outlet of the nozzle. The second fluid passage is in communication with the second outlet of the nozzle. The switch is selectively activated by the trigger upon movement of the trigger. The valve assembly is in fluid communication with the first fluid passage and the second fluid passage. The valve assembly includes a valve and a solenoid. The valve is operable between an open position and a closed position. The solenoid is in electrical communication with the switch and an associated power source. The switch controls the delivery of power to the solenoid and the solenoid operates the valve. A system for applying an electroless plating solution is also disclosed.
