Type 8644 Structure and function of the modules Pneumatic connection modules Feeds in the form of pneumatic connection modules form the fluid interface between the supply line and the internal supply structure. The fluid is passed from one valve segment to the next via the feed. To ensure that the supply pressure over the entire route remains almost constant, additional feeds may be required. It is recommended to set one after 24 (ME02) or 16 (ME03) valve positions. By using intermediate feeds, seg- ments can also be created if the pneumatic channels between individual valve segments are closed.
