Δp (bar)

Q (l/min)

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

/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:

Δp1 = Δp x (Q1/Q)

where Δp will be the value for the losses for a specific flow rate Q which can be obtained from

the diagram, Δp1 will be the value of the losses for the flow rate Q1 that is used.

The ARON NG6 directional control valves 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).

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

casting whilst the coil is kept in position by a ring nut.

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. To improve the valve performance, different springs are used for each

spool.

The solenoids, constructed with a protection class of IP65 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 ADC.3 valve uses shorter solenoids than the standard AD.3.E to reduce the overall

dimensions.

The solenoid coils are normally arranged for DIN 43650 ISO 4400 type connectors (standard

version). On request, could be available the following coil connection variants: AMP Junior

connections; flying leads connections, with or without integrated diode; Deutsch connections

with bidirectional integrated diode.

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

≥75.

The tests have been carried out with solenoids 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

/s at 40 degrees 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 are used with the flow

in one direction only, the limits of use could have variations

which may even be negative (See curve No 4 and Spool No

15-16). The tests were carried out with a counter-pressure

of 2 bar at T port.
