SYMBOL:
SV12-34 Valve symbol
DESCRIPTION
A solenoid-operated, 3-way, spool-type, direct-acting, screw-in hydraulic directional
cartridge valve intended for bi-directional blocking applications.

OPERATION
When de-energized, the SV12-34 allows flow between 2 and 1 while blocking flow at 3.
When energized, the cartridge’s spool shifts to open flow between 3 and 2, while blocking 1.

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