SV08-47E Valve

SYMBOL:
SV08-47E Valve symbol
DESCRIPTION
A solenoid-operated, 4-way, 3-position, direct-acting, screw-in hydraulic cartridge valve.

OPERATION
When de-energized, the SV08-47E blocks flow at 3 and 4, while allowing flow from 2 to 1. When coil S1 is energized, the spool shifts to allow flow from 3 to 4 and 2 to 1. When coil S2 is energized flow is allowed from 2 to 3 and from 4 to 1. In circuits where work port flows are unequal due to cylinder ratios, the higher return flow should be directed to port 2.
NOTE: While 1 may be fully pressurized, it is not intended for use as the valve’s inlet.

FEATURES
• Continuous-duty rated solenoid.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Optional waterproof E‑Coils rated up to IP69K.
• Efficient wet-armature construction.
• All ports may be fully pressurized.
• Cartridges are voltage interchangeable.
• Unitized, molded coil design.
• Industry-common cavity – compact size.
