Product Description

A solenoid-operated, 4-way, 2-position, direct-acting spool-type, screw-in hydraulic cartridge valve.

Product Operation

When de-energized, the SV08-40 flow paths are ➂ to ➁, and ➃ to ➀When energized, the valve’s spool shifts to open ➂ to ➃, and ➁ to ➀. All ports are open at cross-over.
Operation of Manual Override Option: To override, push button in and twist
counterclockwise 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 fullest 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.
