ABSTRACT:
A high-flow, pneumatically-controlled hot melt adhesive applicator valve assembly comprises a housing which includes a lower module body within which a die orifice is defined. A ball valve member is operatively associated with the die orifice, and a hot melt adhesive charge passageway is provided within the module body so as to fluidically conduct the hot melt adhesive to the die orifice. A middle-air cylinder is disposed atop the module body and defines a first cylinder chamber therein, and an upper-air cylinder is disposed atop the middle-air cylinder and defines a second cylinder chamber therein. The valve member is fixedly mounted upon the lower end of a piston rod, and first and second pistons are fixedly mounted upon axially central and upper end portions of the piston rod so as to define with the piston rod and the first and second cylinder chambers a dual-piston multiplier assembly. OPEN and CLOSE air passageways are fludically connected to the cylinder chambers so as to actuate the dual-piston multiplier assembly vertically upwardly or downwardly so as to move the valve member accordingly. The middle-air cylinder includes an internal OPEN air passageway such that OPEN air is simultaneously fludically connected to the first and second cylinder chambers so as to simultaneously actuate the first and second pistons of the dual-piston multiplier assembly.
