– The pilot control of the solenoid coils is operated with
a regulated external pilot air supply.
– The valve terminal is fitted with the following valve sub-
bases and, in some cases has two pressure zones.
Valve sub-bases
Pressure zone with vacuum or
low pressure supply The pressure zone must be equipped only with the following valve
sub-bases:
– 5/2-way valve, monostable (ident. code M)
– 5/2-way valve, double solenoid (Ident. code J)
– 5/3-way valve (ident. code B, E and G)
– 3/2-way valve (Ident. code W and X) (see also subsequent note).
– 2/2-way valve (ident. code R and S)
The valve sub-bases with Ident. code N, K and H, if supplied via port
(1), are
not suitable for vacuum/low pressure!
Pressure zone with excess
pressure supply
1)
via port (1)
The pressure zone can additionally be equipped with the following
valve sub-bases:
– 2x3/2-way valves (Ident. code H, K and N)
1)
In accordance with diagrams in Appendix A, Fig. A/1
Tab. 3/5: Valve sub-bases
Note
3/2-way valves with ident. code W and X:
2/2-way valves with ident. code R and S:
– These valves can be supplied individually and therefore
operated in the pressure range of -0.9 … 10 bar. They are
independent of supply port 1 of the valve terminal. The
ports via which these valves are supplied with com-
pressed air or vacuum and via which exhaust air is re-
moved are shown in Appendix A, Tab. A/6, or Tab. A/7.
The above mentioned valves are supplied with pilot air via
port 12/14 of the valve terminal.
