Abstract: An air-assisted airless spray gun (10) includes a valve cartridge (44, 46) configured to control a flow of air or spray fluid through the spray gun (10). The valve cartridge (44, 46) includes a housing configured to interface with the spray gun body (12) and fully supporting the flow control components (76, 78, 80) of the valve cartridge (44, 46). The housing is secured within a bore (48, 50) of the spray gun body. The valve member (76, 78, 80) is supported by the housing and actuatable relative to a seat. The valve (76, 78, 80) is formed between the seal end of the valve member and the seat.
