A two component spray gun with low/high flow rates allows the operator to spray in confined areas at lower flow without having to change the mix module. The lower flow reduces undesirable “spray back” and will also help reduce material waste. Pneumatic piston 12 travel, which determines on/off fluid flow, can be selected on the fly to either close the fluid ports 14 which stops fluid flow, partially open the fluid ports 14 which limits fluid flow, or to fully open the fluid ports 14 to allow for maximum flow. Pneumatic piston 12 travel can be limited by ...
1. A plural component air purge spray gun having fluid ports, the plural component air purge spray gun comprising: a pneumatic piston positioned to selectively cover said fluid ports and moveable between a closed position preventing flow through said ports, a partially open position allowing a limited amount of flow through said ports and a fully open position allowing full flow through said ports;a mechanical stop plunger selectively positionable to limit travel of said piston to one of said positions;a stop bar configured to rest within and movable bet...
