2/2 Way Solenoid Operated
Directional Control Valves Poppet
Type
SD3E-A2
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 AC applications 120 V/ 60 Hz or
230 V/ 50 Hz. With the AC high power solenoid coils, the
rectifiers are integrated directly in the connector. 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.
