摘要

A plural component spray nozzle comprising a nozzle block having two feed passageway and a main passageway. The main passageway is configured to receive one material through each feed passageway. There is a receiver block having two receiver channels. Each receiver channel comprises an entry port on one end and an exit port on another end. The receiver block is configured to selectively receive the nozzle block in actuated or blocked position. In the actuated position, the exit ports of the receiver channels are fluidly connected with their corresponding feed passageways. In the blocked position, the exit ports of receiver channels are fluidly blocked with their corresponding feed passageways.
