2/2 Way Solenoid Operated
Directional Control Valves Poppet
Type
SD3E-B2
The pilot operated 2/2 way solenoid actuated poppet
valves control in the first line the start and stop function of
the oil flow. The valve consists of the valve bushing (1),
main control spool (2), return spring (3), cartridge with
actuating system (4) and of the solenoid coil (5) that is
mounted on the actuating system. The valve bushing is
screwed into the cartridge part.
In the variant normally closed / normally open, the valve
is securely held in the respective basic position by a
spring. By energizing the solenoid coil the spring force is
overcome and the pilot valve is pressed onto the seat or
lifted. Opening and closing of the main control spool is
hydraulically supported through the orifice boring
created in the main control spool.
The DC solenoid coils can be delivered for 12 V and 24 V
supply voltages.
For the alternating current supply, either of 120V/60Hz or
230V/50Hz voltage, the relevant rectifiers for the C19 coil
types are available in the auxiliary connector. For the
C22 coil types and AC voltage design, the rectifiers are
integrated directly into the connector base. . By
loosening the fixing nut (6), the solenoid coil can be
replaced or turned in the range of 360°.
Notice.
The valves are supplied without solenoids coils. The
solenoid coil, the terminal box and the body for line
mounting have to be ordered separately.
