Valve block assembly for I.S. glassware machine and modular pilot valve operated poppet valve assembly

A valve block assembly for an I.S. glassware forming machine which comprises:

• a cartridge block and a plurality of pilot valve operated poppet valve assemblies mounted wherein said cartridge block, each of said pilot valve operated poppet valve assemblies having a supply air port, an operating air out port and an exhaust passage, and a wireway enclosure for holding an associated wiring harnesses within the envelope thereof and for mounting associated controls.

A modular pilot valve operated poppet valve assembly for use with an associated valve block assembly of an associated glassware manufacturing machine which comprises:

• a solenoid control valve having an input port for connection to an associated source of pilot air and an outlet port, said solenoid control valve having a first position and a second position, said position changing in response to being energized;
• and
• a poppet valve having a first port for connection to an associated source of control air, a second port for connection to associated apparatus being controlled and a third port for exhaust air passing from the associated apparatus being controlled, and a poppet, said poppet having an axes and being mounted for axial movement responsive to air pressure at said outlet port of said solenoid control valve, said poppet being axially movable between a first position in which said first and second ports are in fluid communication and a second position in which said second and third ports are in fluid communication, said modular pilot valve operated poppet valve assembly having exterior surfaces that are substantially cylindrical.
