Abstract
A valve assembly () which is intended for differentiated individual control of the movement mechanisms of an IS machine and can therefore be used in a modular manner consists of a valve support (') and a head part () which supports two pilot control valves (), two safety valves () and two switching valves as one assembly. By way of actuation of the safety valves (), the feed of control air to the switching valves can be interrupted, which switching valves are assigned, for example, to the opening movement and the closing movement, respectively, of a closing cylinder which is assigned to a preform. The valve assembly has interfaces for connection of control and operating air and for electric connection to a machine controller. If required, the assembly which is designed in this way makes it possible to interrupt the control air in a differentiated way which is related to an individual track, in addition to simple assembly and dismantling.
