Abstract
A valve stack assembly comprising a manifold having an inlet channel connected to a source of air. A plurality of inlet tubes each having an inner end communicating with said inlet channel and the outer end of each tube projects outwardly of the manifold and is sealed within an inlet passage of a valve. An annular collet is disposed in each inlet passage and receives the inlet tube and the collet is designed such that the tube can be freely inserted in the collet but cannot be freely withdrawn unless the collet is moved axially inward to a release position. Each valve also includes an outlet opening which receives an outlet tube mounted in the manifold and each outlet tube is connected to a transverse manifold passage which in turn is connected through a fluid line to a working element.
