A modular coatings sprayer includes a valve housing in which there is defined a nozzle orifice, a valve-shaft bore opposite the nozzle orifice, and an internal fluid passage The housing side wall includes an opening through which pressurized fluid is introduced into the fluid passage A valve shaft with opposed back and nozzle closing ends is sealably supported within the bore such that the valve shaft can axially reciprocated between a first position in which the nozzle-closing end does not seal the nozzle orifice and a nozzle-closing position in which the nozzle-closing end seals the nozzle orifice The valve housing is configured for selective cooperative coupling to a valve-actuating assembly having a body and a lever mounted for pivotable movement relative to the body The lever selectively engages a portion of the valve shaft external to the valve housing. |
