SV12-31 Spool, 3-Way
DESCRIPTION
A solenoid-operated, 3-way, direct-acting spool-type, screw-in hydraulic cartridge
valve.
OPERATION
When de-energized, the SV12-31 allows fl ow between ➁ and ➀ while blocking fl ow
at
➂. When energized, the spool shifts to allow fl ow between ➀ and ➂ while blocking
fl ow at
➁.
While port
➀ may be fully pressurized, it is not intended to be used as the inlet.
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 waterproof E-Coils rated up to IP69K.
