Solenoids
The operating solenoids are DC solenoids. For AC supply the solenoids are provided with rectifier which are 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 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, 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.

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.
Special Configurations C3
Always without X plug
C3
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
