SV12-41 Valve

SV12-41 Valve symbol
A solenoid-operated, two-position, four-way, direct-acting spool-type, screw-in hydraulic cartridge valve, intended as a bidirectional blocking valve.

When de-energized, the SV12-41 blocks flow at all ports. When energized, the spool shifts to allow flow from 3 to 4, and from 2 to 1.
NOTE: Consult factory for applications where port 1 will be used as an inlet.

• Bidirectional operation.
• 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.
