2.8.6 Creation of pressure zones
To supply valves with different operating pressures, pressure zones can be created in the valve termin
al. A total of up to 20 pressure zones can be created.
To operate vacuum- or low-pressure-compatible valves with other valves, pressure zones are essential
èChap. 2.8.3.
Sub-bases with pressure zone separation divide the supply duct (1) and/or the exhaust air ducts (3)
and (5) èChap.2.4.5).
A pressure zone starts to the right of the sub-base with pressure zone separation and requires its own
pressure supply. Compressed air can be supplied and exhausted via a supply module or the right end
plate. Additional supplies can be installed at any desired position within a pressure zone è Fig. 2.25
and Fig. 2.26.
