A modular coatings sprayer includes a valve housing in which there is defined a nozzle orifice and a valve-shaft bore opposite the nozzle orifice. A housing side wall extends between the orifice and bore and defines an internal fluid passage. The side wall includes an opening through which pressurized fluid is introduced into the fluid passage. A valve including a valve shaft with opposed back and nozzle-closing ends is sealably supported within the bore such that (i) the nozzle-closing end is situated within the housing and the back end is situated external to the housing and (ii) 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 such that pressurized fluid within the fluid passage is prevented from exiting through 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 such that (i) when the lever is pivoted in a first direction, the valve shaft is axially displaced in order to open the nozzle orifice and (ii) when the lever is pivoted in a second direction, the valve shaft is axially displaced toward the nozzle-closing position. |
