2.105.1

Solenoid valves series A2

1/4”, with multiple connector

Series of spool valves, for multi-pole connection on island  sub-
base.
This series of modern valves are innovative and highly performing:
•   With reduced overall dimensions and high flow rates;
•   Electric pilots on solenoid / solenoid version are both on same

side;

• Coils with low power consumption;
•

Possibility of feeding with different pressures different valves
( by integrating a membrane module within the base );

• Can be set for separate internal feeding;
• Fast and practical assembly: each valve, even if in an interme-

diate position, can be easily replaced by individually operating on
such valve only;

• “Push” manual override, spring return and two position;
• With LED.

Solenoid valves series A2

Sub-bases, accessories, SUB-D connector

Sub-bases with fix position for A2 series valves, with standard
25 poles SUB-D connector, can be mounted on DIN EN 50 035
guides.
On each base, one position on the opposite side of the SUB-D
connector is dedicated to the module for the external piloting of the
valves.
The main feeding of the valves ( 1 ) can be divided by applying an
internal diaphragm, in case feeding with two different pressures
should be required.
Likewise, the exhausts ( 3 – 5 ) can be divided with the suitable
diaphragms.
The base is mainly composed by aluminium, anodized to grant last
in time.
The covers in PBT glass charged, are sealed with an internal o-ring
to protect the electrical circuit from external atmospheric agents.

G 1/8

The pneumatic feeding to the valve pilots mounted on the island, is
by a feeding module, which takes on the base a dedicated position,
on the opposite side of the SUB-D connector.

The module can be:
• Internal piloted, when the piloting pressure is the same as the

main feeding on;

• External piloted, when the piloting pressure and main feeding on

1 are differentiated.

To complete the range, there is the blanking module for the unused
position. The electrical connection in this case will be protected by
a suitable plug.

The valve units A2 can work with two zones of different pressures by using blanking diaphragms:

• Diaphragm for differentiated main feeding: In case two different pressures should be needed on the same island and feeding

two separated groups of valves. In this case base should be fed on both sides;

• Diaphragm for differentiated exhausts: In case is necessary to separate the exhausts on 3 or 5 or both. This way, the exhausts

of two groups of valves can be conveyed separately;

Both types of diaphragms can be mounted without occupying any valve position on the base and for this reason they can be
applied also later.

Solenoid valves series A2

Coding and code

The encoding of the islands is by using a code which identifies
the sequence of components mounted on the base:
after having determined which types and how many valves are
needed, considering also eventual position to let unused, is pos-
sible to determine the number of positions of the base, internal or
external feeding to the pilots and the tension.
The valves and diaphragms, identified with letters will complete
the island encoding: the order of the letters will reflect the effec-
tive position of each component on the base.

The sequence of the positions start from the side of the SUB-D
connector and end on the side of the external piloting module.

The position of the external piloting module is set, on the opposite
side of the SUB-D, so is not necessary to indicate in the code
that position.

Solenoid valves series A2

Electric scheme of multiple connector 25 poles

The transferring of the signals from the PLC to the valves is through a multi-pole connector capable of manage 24 signals.
Such signals are distributed to the valves following the scheme hereunder.
Peculiarities of these valves are:

•  Simplicity of the electrical connection with each valve configuration;
•  Type of valve will not limit the maximum number of valves applicable;
•  Every type of valve can replace another maintaining the same electrical connection.
