The RNEH solenoid operated - hydropiloted valves are
consisting of an RPE3-06 type solenoid operated
directional control valve (see data sheet HA 4010) that
operates a 4-way hydropiloted control valve with a
connection surface in accordance with the ISO 4401
standards. They are available in various configurations
and spool types.
The pilot and the drain connections can be made internal
or external by inserting or removing the accordant
threaded plugs located in the main directional control
valve.
A wide range of configurations and different solenoid
operated - hydropiloted directional control valve spool
positions are available:
– 4-way, 3-position directional control valve, with two
solenoids; positioning of the spool in center position is
obtained with centering springs.
– 4-way, 2-position directional valve, with one solenoid
and one return spring or two solenoids and detent of the
spool position.
The basic surface treatment of the valve housing is
phosphate coated and the solenoids are zinc coated.

Ordering Code
Note:
Piloting must always be external for valves with the H11 type pilot valve (available on request). Also valve must have external
piloting for spools with P and T connected in the center position. Internal piloting is possible only with a C3 version valve (see
page 7), or by installing a check valve with a setting of min. 5 bar on the outlet line. In this case the valve must have external
drainage.
Piloting must always be external for valves with the RNH type hydraulic control valve (available on request).

Solenoids
The operating solenoids are DC solenoids. For AC supply the solenoids are provided with rectifier which are integrated in the
EN connector socket as part of the solenoid. The connectors can be turned by 90°. By loosening the nut, the solenoids can be
turned or replaced without interfering with any seals of the valve.
In the case of solenoid malfunction or power failure, the spool of the valve can be shifted by manual override, provided the
pressure in T-port does not exceed 25 bar.
The values indicated refer to a solenoid valve operating with piloting pressure 100 bar, with mineral oil at a temperature of
40 °C, a viscosity of 32 mm
2
/s and with PA and BT connections. The switch on times are obtained from the time the spool
switches over. The switch off times are measured at the time pressure variation occurs in the line.

Solenoid control: RNEH
The valve is supplied with a pilot solenoid
valve type RPE3-06.
Controls
Control of the main spool shifting speed: D
By placing a 2VS3-06 type double flow control valve between the pilot solenoid valve and the hydropiloted valve, the piloted
flow rate can be controlled and therefore the shifting speed can be varied. Add the letter D to the identification code to
request this device.
Type of Command
Manual Override
Whenever the solenoid valve installation may involve exposure to atmospheric agents or be used in tropical climates,
the manual override, boot protection is recommended. Add the suffix N1or N2 to request this device.
Electrical Connector
The solenoid valves are never supplied with connector. Connectors must be ordered separately.
Special Configurations C3
Check valve incorporated on line P: C3
Valve RNEH is available upon request with check valve incorporated on line
P. This is particularly useful to obtain the necessary piloting pressure when
the main control valve, in the rest position, has line P connected to the T
outlet. The cracking pressure is 5 bar. Add C3 to the identification code for
this request.
C3 version is available only with internal pilot.

Installation
Configurations with centering and recall springs can be mounted in any position; type J17, J27 valves - without springs and
with mechanical retention must be mounted with the longitudinal axis horizontal. Valve fastening takes place by means of
screws or tie rods, placing the valve on a flat surface, with values of planarity and smoothness that are equal to or better
than those indicated in the drawing. If the minimum values of planarity or smoothness are not met, fluid leakages between
valve and mounting surface can easily occur.
Service valve without range stated parameter consultation with manufacturer.
