SV08-44 Spool, 4-Way, 2-Position (SV08-44)
A solenoid-operated, 4-way, 2-position, direct-acting, spool-type, screw-in hydraulic cartridge valve.
Product Operation
When de-energized, the SV08-44 allows flow from ➂ to ➃, and from ➁ to ➀When energized, the spool shifts to allow flow from ➂ to ➀, while blocking ➁ and ➃Operation 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.
