SYMBOL:
SV10-25 Valve symbol

DESCRIPTION
A solenoid-operated, 2-way, normally open, spool-type, direct-acting, screw-in hydraulic cartridge valve, for bi-directional blocking applications.

OPERATION
When de-energized, the SV12-25 allows flow in both directions. When energized, the cartridge’s spool lifts to block flow in both directions.

FEATURES
• Continuous-duty rated coil.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Both ports may be fully pressurized.
• Heavy-duty water resistant E-Coils rated up to IP69K.
