SV12-24 Spool, 2-Way, Normally Closed
DESCRIPTION
A solenoid-operated, two-way, normally closed, direct-acting spool-type, screw-in
hydraulic cartridge valve, designed to function as a bidirectional blocking valve.
OPERATION
When de-energized, the SV12-24 blocks fl ow in both directions. When energized, the
valve’s spool shifts to allow fl ow in both directions.
FEATURES
• Continuous-duty rated solenoid.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• All ports may be fully pressurized.
• Heavy-duty water resistant E-Coils rated up to IP69K.
