VALVE BLOCK ABSTRACT OF THE DISCLOSURE A compact valve block for an IS glass forming machine in which a plurality of vertically positioned poppet valves which are in two rows and in staggered array, are con- trolled by solenoid operated pilot valves of equal number to the poppet valves. An air manifold communicates with all of the poppet valves and the air is selectively delivered to the "kiss block" of an IS machine to provide the functional operation of various mechanisms on the machine. The de- energization of the solenoid operated pilot valve associated with any of the poppet valves permits the poppet valve to return under spring pressure to connect its output passage to an exhaust passage. All the exhaust passages on all of the poppet valves enter a common header which in turn communicates with an exhaust chamber, thus muffling the sound of air normally associated with the exhaust of the pneumatic motors of an IS machine.
