DESCRIPTION
A solenoid-operated, 2-position, 4-way, spool-type, direct-acting, screw-in hydraulic
directional valve.

OPERATION
When de-energized, the SV12-40R allows flow from 2 to 1, and from 3 to 4. When energized,
the cartridge’s spool shifts to open flow from 3 to 2, and from 4 to 1.
NOTE: Consult factory for applications where port 1 will be used as an inlet.

FEATURES
• Continuous-duty rated coil.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Manual override option.
• All ports may be fully pressurized.
• Heavy-duty waterproof E‑Coils rated up to IP69K.
