DESCRIPTION
A solenoid-operated, 4-way, 2-position, direct-acting, spool-type, screw-in hydraulic
cartridge valve.
OPERATION
When de-energized, the SV08-44 allows fl ow from ➂ to ➃, and from ➁ to ➀.
When energized, the spool shifts to allow fl ow from
➂ to ➀, while blocking ➁ and ➃.
Operation of Manual Override Option: To override, push button in and twist counter-
clockwise 180°. The internal spring will push the button out. In this position, the valve
may be only partially shifted. To assure full override shift, pull the button out to its full-
est extension and hold it in this position.
To return to normal valve function, push button in, twist clockwise 180°, and release.
Override will be detented in this position.
Note: While
➀ may be fully pressurized, it is not intended for use as the valve’s inlet.
FEATURES
• Continuous-duty rated solenoid.
• Hardened precision spool and cage for long life.
• Optional coil voltages and terminations.
• Effi cient wet-armature construction.
• All ports may be fully pressurized.
• Cartridges are voltage interchangeable.
• Manual override option.
• Optional waterproof E-Coils rated up to IP69K.
• Unitized, molded coil design.
• Compact size.
