Ordering Code
Installation Note:
- It is necessary to ensure minimum pilot pressure, that is why either external piloting or option C3 (check valve in P port) must be used for spools
which have connection between P and T ports (H11, C11, R52, X52, J27). In this case, the valve must be externally drained.
- Attention: spools J17, J27 may assume an undefined position without energy supply.
- For directional valves with two solenoids, one solenoid must be de-energized before the other solenoid can be energized.
- The AC coils correspond to E5 solenoid electrical terminal.
- For other solenoid voltages see datasheet HA 8007.
- The solenoid operated valves are delivered without connectors. For connectors see datasheet HA 8008.
- Configurations with centering and recall springs can be mounted in any position; J17, J27 valves - without springs or mechanical
retention - must be mounted with the longitudinal axis in the horizontal.
- Other special versions are available. Consult our technical department.

Pilot and Drain
Electrical Features
Solenoids
The operating solenoids are DC solenoids. For AC supply, the solenoids are provided with a rectifier integrated in the DIN 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 case of a solenoid malfunction or power failure, the spool of the valve can be shifted by manual override, provided
the pressure in port T does not exceed 25 bar.
For detail information on the pilot valve RPE3-06 refer to datasheet No. 4010.
Actuation in millimeters (inches)
Solenoid control: RNEH
The valve is supplied with an RPE3-06 pilot solenoid valve.
Hydraulic control: RNH
The valve is supplied with a cross-connection cover plate.
X and Y connections are used for the hydraulic control of the valve.
Check Valve incorporated in Line P
The RNEH valves are available with pilot and drain, both internal and external. The version with external drain allows for a higher back pressure on the outlet.

Y: plug M6x8 for external drain
Valves RNEH are available with a back pressure valve incorporated
on line P (Type „C3“). This is necessary to obtain the piloting pressure when the control valve
(in the rest position) has the line P connected to the port T (spools H11, C11, R52, X52, J27).
The cracking pressure is 5 bar with a minimum flow rate of 15 l/min.
Add „C3“ to the identification code for this request
(see „Ordering Code“ section).
The preloading check valve is a part of body of the controlled valve size 25
and cannot be ordered separately.
The minimum piloting pressure can be as low as 5 bar at low flow rates, but with higher flow rates a pressure of 12 bar is needed.
If the valve operates with higher pressures it is necessary to use the version with external pilot and reduced pilot pressure.
Otherwise, the valve with internal pilot and a pressure reducing valve with a 30 bar fixed setting can be ordered.
In the C3 version the piloting is always internal.
The back pressure valve can’t be used as a check
valve because it doesn’t guarantee sealing.

Solenoid operated distributor with pilot valve in configuration 3H11
It is possible to deliver the solenoid operated distributor with the pilot valve in configuration 3H11 (all the ports at the outlet). This configuration
is used with external piloting in order to allow the unloading of the piloting line when the solenoid operated valve is in the rest position.
With this option, the piloting is necessarily external.
Control of the main spool shifting speed: D
By placing a 2VS3-06 flow control valve between
the pilot solenoid valve and the hydropiloted valve, the pilot flow
rate can be controlled and therefore the shifting speed adjusted.
Add the letter D to the identification code to request this device.
Pilot pressure reducing valve - 30 bar fixed setting: Z
Internal piloting with mounted pressure reducing valve
with 30 bar fixed setting. The option Z may be used together
with option D.
Control of the main spool stroke: C
Using special side plugs, it is possible to introduce stroke control the piloted
valve so as to vary the maximum spool opening clearance. This solution allows
the control of the flow rate from the pump to the actuator and from the
actuator to the outlet, resulting in double adjustable control of the actuator.
Add the letter C to the identification code to request this device.
Shifting speed control: PF
with an orifice (0,8 mm) in port P of the solenoid pilot valve
