CONTROL
The intermediate plate cod. W is composed by a subbase which is equipped with a upper connection bracket. On this bracket there
are two connections on which it is possible to apply two different pressures (ex. P2 and P3). In this configuration, the connection
1 on the subbase represents the exhaust 3/5. With this plate it is possible to supply the valves positioned downstream through the
exhausts 3 and 5. When supplied from the exhausts, these valves have a different function compared with the ones supplied in the
standard way. Some examples:
Solenoid valve mod. C at rest has outlets 2 and 4 active and corresponds to model “A”, in presence of electrical inputs 12 and
14 outlets 2 (P3) and 4 (P2) close respectively; the configuration of solenoid valve mod. V at rest doesn’t change, in presence of
electrical input 12 outlet 4 (P2) is activated, in presence of electrical input 14 outlet 2 (P3) is activated; outlets 2 and 4 are closed in
solenoid valve mod. A at rest which corresponds to model “C”, in presence of electrical inputs 12 and 14 outlets 2 (P3) and 4 (P2)
open respectively; outlet 4 (P2) is active in solenoid valve mod. M at rest, in presence of electrical input 14 the active outlet becomes
outlet 2 (P3). All the valve functions, both 10.5 and 21 sizes, have this different operation. Solenoid valves with an integrated
pressure regulator can’t be used after an intermediate plate W. This plate requires in the initial part of the valve island a supply
pressure of 4 bar at least. Otherwise, it is necessary to use the version with external servo pilot supply and apply a pressure of at
least 4 bar on the connection 12/14. It is necessary to insert a seal type T before plate W.
PROPER USE OF VALVE FUNCTIONS WITH INTERMEDIATE PLATE TYPE W
The subbases for valves Size 1 (10.5 mm) are set for housing
2 solenoid valves that may be both with double solenoid.
Each subbase uses 4 electric signals. Even in case of
monostable solenoid valves the subbase uses 4 electrical
signals.
To increase the number of valve positions that can be
connected with a single Sub-D connector, all the subbases
Size 1 can add “Z” at the end of their code thus using
2 electrical signals. They are, therefore, suitable for the
connection of monostable solenoid valves.
Examples:
Code A --> AZ with board for monostable solenoid valves
Code N --> NZ with board for monostable solenoid valves
