ABSTRACT:
A compact spray gun using a single air supply port to actuate two piston valves and act as an air refinement system. An externally adjustable cartridge type packaging assembly needle piston valve seals the resin. A spool valve portion of a catalyst piston valve having O-ring seals is separable external from the piston portion. Leak detection ports are provided so the operator can easily determine when to adjust or replace the packing or O-ring seals. The catalyst piston valve controls the mixing of the catalyst and air from a second air supply port. In a preferred embodiment, the resin piston valve controls a valve which provide air to the chopper system simultaneously with spraying of the resin.
