Note
Valves with Ident. code I, 2 x 2/2−way valves:
With these valves, vacuum is supplied at connection (5).
Solenoid coil 14 switches the vacuum to connection (4)
The operating pressure at supply connection (1) can be
used as an ejector pulse at connection (2). The operating
pressure is switched to connection 2 with solenoid coil 12.
If the valve terminal is also equipped with other valves,
then operate these vacuum and low pressure valves in a
separate pressure zone with a separate exhaust duct (5).
Valves with Ident. codes W and X, 3/2−way valves:
These valves can be supplied individually and therefore
operated in the pressure range of −0.9 ... 10 bar. They are
independent of supply connection (1) of the valve terminal.
The connections via which these valves are supplied with
compressed air or vacuum and via which exhaust air is
removed are shown in Tab. 3/2.
The pilot air is supplied via the valve terminal.
