DIRECTIONAL CONTROL VALVES CETOP 3/NG6
INTRODUCTION
The ARON directional control valves NG6 are designed for subplate mounting with an
interface in accordance with UNI ISO 4401 - 03 - 02 - 0 - 94 standard (ex CETOP R 35 H
4.2-4-03), and can be used in all fields on account of their high flow rate and pressure
capacities combined with compact overall dimensions.
The use of solenoids with wet armatures allows a very practical, safe construction completely
dispensing with dynamic seals; the solenoid tube is screwed directly onto the valve chest
whilst the coil is kept in position by means of a lock nut.
The special, precise construction of the ports and the improvement of the spools enables
relatively high flow rates to be accommodated with a minimal pressure drop (∆p).
The operation of the directional valves may be electrical, pneumatic, oleodynamic, mechani-
cal or lever.
The centre position is obtained by means of calibrated length springs which reposition the
spool in the centre or end of travel position once the action of the impulse is over.
The solenoids are constructed with a protection class of IP66 to DIN 40050 standards and are
available in either AC or DC form in different voltage and frequencies.
The new type DC coil "D15", of cause their high performance, allows to increasing the limits
of use respect to last series.
All types of electrical control are available, on request, with different types of manual
emergency controls.
The solenoid coils are normally arranged for DIN 43650 ISO 4400 type connectors; is available
on request these variant coils: with AMP Junior connections, with AMP junior and integrated
diode, with Deutsch DT04-2P connections or solenoid with flying leads. Connectors with built
in rectifiers or pilot lights are also available.
The valves are designed for use with DIN 51524 standard hydraulic mineral oils and it is
recommended that filters should be fitted to ensure a maximum contamination level of class
10 in accordance with NAS 1638, ß

≥75.
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.

AD.3.E... DIRECTIONAL CONTROL VALVES SOLENOID OPERATED CETOP 3/NG6
The tests have been carried out with solenoids at operating temperature and a voltage 10% less than rated voltage with a fluid temperature
of 40°C. The fluid used was a mineral oil with a viscosity of 46 mm
2
/s at 40°C. The values in the diagram refers to tests carried out with the
oil flow in two directions simultaneously T = 2 bar (e.g.. from P to A and the same time B to T). In the case 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. Rest times: the values are indicative and
depend on following parameters: hydraulic circuit, fluid used and variations in hydraulic scales (pressure P, flow Q, temperature T).
DIRECT CURRENT SOLENOIDS (DC) ALTERNATING CURRENT SOLENOIDS (AC)
Direct current: Energizing 30 ÷ 50 ms.
De-energizing 10 ÷ 30 ms.
LIMITS OF USE (MOUNTING C-E-F)
Alternating current: Energizing 8 ÷ 30 ms.
De-energizing 15 ÷ 55 ms.
A max. counter-pressure of 8 bar at T is permit-
ted for the variant with a microswitch (M1).

Valves type AD3.E... variant J* with spool movement speed control
These ON-OFF type valves are used a lower spool movement speed
than usual for conventional solenoid valves is required to prevent
impacts which could adversely affect the smooth running of the
system. The system consist of reducing the transfer section for the fluid
from one solenoid to the other by means of calibrated orifices.
• This version can only be used with a direct current (DC) and also
involves a reduction in the limits of use so that we suggest to
always test the valve in your application
• To order AD.3.J* version valves, specify the orifices code.
• The operation is linked to a minimum counter-pressure on T line
(1 bar min.)
• The switching time referred to the spool travel detected by a LVDT
transducer can vary for the NG6 valve from a minimum of 100 to a
maximum of 300 ms depending on 5 fundamental variables:
1) Diameter of the calibrated orifices (see table)
2) Hydraulic power for clearance referring to flow and pressure values
through valve
3) Spool type
4) Oil viscosity and temperature
5) Counter-pressure at T line
• Possible mountings: C / E / F / G / H
• 16 / 19 / 20 / 21 spools not planned for AD3E variant J*
