PRESSURE DROPS
The diagram at the side shows the pressure drop
curves for spools during normal usage. The fluid
used is a mineral oil with a viscosity of 46 mm
2
/s at
40°C; the tests have been carried out at a fluid
temperature of 40°C. For higher flow rates than
those in the diagram, the losses will be those
expressed by the following formula:
∆p1 = ∆p x (Q1/Q)
2
where ∆p will be the value for the losses for a
specific flow rate Q which can be obtained from the
diagram, ∆p1 will be the value of the losses for the
flow rate Q1 that is used.

ADP. 5.E... DIRECTIONAL CONTROL CETOP 5/NG10
HIGH PERFORMANCES SOLENOID OPERATED VALVES
The ARON NG10 directional control valves are designed for subplate mounting with an
interface in accordance with UNI ISO 4401 - 05 - 04 - 0 - 94 standard (ex CETOP R 35 H
4.2-4-05). The use of solenoids with wet armatures allows an extremely safe construction
completely dispensing with the need for dynamic seal. The solenoid tube is screwed directly
onto the valve casing whilst the coil is kept in position by a ring nut. Great care has been taken
over the design and production of the ducts and the improvement of the spools allows relatively
high flow rates to be accommodated for its size with minimal pressure drops (∆p). The
operation of the directional valve is electrical. The centring is achieved by means of calibrated
length springs which, once the impulse is over, immediately reposition the spool in the neutral
position. The solenoids, constructed with a protection class of IP66 in accordance with BS
5490 standards, are available in direct current form and different voltage. The electrical
controls are equipped with an emergency manual control inserted in the tube.
The ADP.5.E.. valve has certain design features which allow it to “manage” a hydraulic power
equal to Q = 120l/min with a P = 320 bar, maintaining a considerable safety margin. These
features can be summarized as follows:
- Solenoid D19 with an optimum ratio between the power absorbed (42W) and the magnetic
force
- Diameter of the spool 18 mm, with carefully designed geometry improved to compensate for
the flow forces
- Compact graphite cast iron valve casing with high mechanical resistance
- Different springs, improved according to the features of the spool
The electrical supply connectors meet DIN 43650 ISO 4400 standards; connectors are also
available with built in rectifiers or pilot lights.
The recommended fluids are hydraulic mineral based oils in accordance with DIN 51524 and
it is recommended that filters should be fitted to ensure a maximum contamination level of
class 10 in accordance with NAS 1638, ß
25
≥75.
For other fluids please contact our Technical DPT.
• The solenoids are in DC voltage only

The tests have been carried out with solenoids at operating
temperature and a voltage 10% less than rated voltage with a fluid
temperature of 50°C.
The fluid used was a mineral oil with a viscosity of 46 mm
2
/s at
40°C.
The values in the diagram refer to tests carried out with the oil flow
in two directions simultaneously (e.g. from P to A and at the same
time B to T).
In the cases where valves 4/2 and 4/3 were used with the flow
in one direction only, the limits of use could have variations
which may even be negative.
The tests were carried out with a counter-pressure of 2 bar at T.

ADP.5.E... Q4 variant - These ON-OFF type valves are used when a
lower spool movement speed is required than it is generally available with
a conventional solenoid valve in order to avoid those shocks which might
otherwise compromise proper system operation. This is obtained by
forcing the fluid to pass through the gap which exists between the screw
thread and the M8x1 tapped thread, restricting in this way the transfer
cross section between the 2 solenoid chambers. Using this variant may
entail a reduction in the operational limits according to the spool used, up
to the complete blocking of the change over itself. The valve operation
depends on the presence of a minimum back pressure on the T line (min.
1 bar). The change over time referred to the spool stroke depends on 4
main variables:
• Applicable hydraulic power, related to the flow rate and pressure
drop across the valve;
• Spool type (system configuration);
• Oil viscosity and temperature;
• Back pressure on T.
