PRESSURE DROPS

INTRODUCTION

DIRECTIONAL CONTROL VALVES CETOP 5/NG10

The ARON directional control valves NG10 designed for subplate mounting with an in-

terface in accordance with UNI ISO 4401 - 05 - 04 - 0 - 94 standard (ex CETOP R 35 H

4.2-4-05), and can be used in all ﬁ elds on account of their excellent capacity and pressure

speciﬁ cations.

The use of solenoids with wet armatures means that the construction is extremely functional

and safe completely dispensing with need for dynamic seals. The solenoid dust cover is screwed

directly onto the valve casing whilst the coil is kept in position by a ring nut.

Great care has been taken in the design and the production of the ducts and the improvement

of the spools has allowed relatively high ﬂ ow rates to be accommodated with minimal pressure

drops (Δp). The operation of the directional valves can be electrical, pneumatic, oleodynamic,

mechanical or lever operated .

The centring position is achieved by means of calibrated length springs which, once the action

of impulse is over, return the spool to the centre or end travel position.

The solenoids constructed with protection class in accordance with DIN 40050 standards

are available in either direct current (IP65) or alternating current (IP66) with different voltage

and frequencies.

All types of electrical controls can be ﬁ tted, on request, with different types of manual emer-

gency controls. The electrical supply takes place through connectors meeting DIN 43650 ISO

4400 standards; connectors are also available with built in rectiﬁ er or pilot lights.

The valves are designed for use with DIN 51524 standard hydraulic mineral oils and it is

recommended that ﬁ lters should be ﬁ tted to ensure a maximum contamination level of class

10 in accordance with NAS 1638, ß

≥75.

The diagram at the side show the pressure drop

curves for spools during normal usage. The ﬂ uid

used is a mineral oil with a viscosity of 46 mm

at 40°C; the tests have been carried out at a ﬂ uid

temperature of 40°C.

For higher ﬂ ow 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 speciﬁ c ﬂ ow rate Q which can be obtained from

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

(*) Pressure dynamic allowed for 2 millions of cycles.

A max. counter-pressure of 4 bar at T is permitted

for the variant with a microswitch (MS).

The tests have been carried out with solenoids at operating temperature and a voltage 10% less than rated voltage with a ﬂ uid temperature

of 40°C. The ﬂ uid used was a mineral oil with a viscosity of 46 mm

/s at 40°C.

The values in the diagram refer to tests carried out with the oil ﬂ ow in two directions simultaneously T = 2 bar (e.g. from P to A and the same

time B to P).

In the cases where valves 4/2 and 4/3 were used with the ﬂ ow in one direction only, the limits of use could have variations which may even be

negative. Rest time: the values are indicative and depend on the following parameters: hydraulic circuit, ﬂ uid used and variations in hydraulic

scales (pressure P, ﬂ ow Q, temperature T).

AD.5.E...J* VALVES WITH SPOOL MOVEMENT SPEED CONTROL VARIANT J*

Valves type AD5.E... with spool movement speed control.

These ON-OFF type valves are used when 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 consists of reducing the transfer section for the ﬂ uid from

one solenoid to the other by means of calibrated oriﬁ ce.

• This version can only be used with a direct current (DC) and also in-

volves a reduction in the limits of use so that we suggest to always

test the valve in your application.

AD.5.E...Q5 VALVES WITH EXTERNAL DRAINING SOLENOID - VARIANT Q5

• To order AD.5.J* version valves, specify the oriﬁ ces code.

• The operation is linked to a minimum counter-pressure on

the T line (1 bar min.)

• The switching time referred to the spool travel detected by a

LVDT transducer can vary for the NG10 valve a minimum of 200

to a maximum of 400 ms depending on 5 fundamental variables:

1) Diameter of the calibrated oriﬁ ce (see table)

2) Hydraulic power for clearance referring to ﬂ ow and pressure

values through the valve

3) Spool type

4) Oil viscosity and temperature

5) Counter-pressure at T line

• Possible mounting: C / E / F / G / H

• 19 / 20 / 21 spools not planned for AD.5.E...J*

E = Manual override

Valves type AD5.E...Q5 with external draining solenoid.

This involves valves with solenoid drainage chambers separated

by line T in the CETOP 5 interface distinguished by the letter L.

This solution makes it possible to operate with a maximum counter-

pressure at T up to 320 bar using only 12.9 material ﬁ xing screws to

ensure the maximum safety of the solenoid valve ﬁ xing and use of

an additional drain. This version can be used for direct current (DC)

and alternating current (AC), but involves a reduction in the limits of

usage depending on the pressure at T.

• Mounting possible: C / D / E / F / G / H / I / L / M
