Valve device for pressure molds, has control mechanism having compressed air controller which lies on same side as diaphragm spring of plunger piston

摘要

The valve device includes a control mechanism which is provided in the extension of a plunger piston (7) on the side which is turned towards a vent hole (5,6). The control mechanism has a compressed air controller which lies on the same side as the diaphragm spring (31) of the plunger piston. The compressed air controller includes a chamber (19), discs (20,22), a ring (21,24), a ring stop (23), and an air pressure channel (25).
