2/2 Way Solenoid Operated
Directional Control Valves Spool
Type
SD2E-A2
The directly operated 2/2 way solenoid actuated spool valve
controls in the first line the start and stop function of the oil
flow. The valve consists of the valve body (1), control spool
(2), return spring (3), cartridge with actuating system (4) and
of the solenoid coil (7) that is mounted on the actuating
system. The valve bushing is screwed into the cartridge part
(4).
The valve bushing is fixed in the cartridge by a wire ring (5)
and sealed with the seal ring (6). Separation of the valve
bushing and the cartridge prevent transmitting the stresses,
which could be caused by too high tightening torques. 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,
the suitable rectifiers for the Light line solenoid coils are
available, with them being mounted in an additional
terminal box. With the high power solenoid coils in AC
variants, the rectifiers are integrated directly in the
connector. By loosening the fixing nut (8), the solenoid coil
can be replaced or turned in the range of 360°. The valve
body is zinc coated.
Note:
The valves are supplied without solenoids coils. The
solenoid coil, the terminal box and the housing body for line
mounting have to be ordered separately.
