Product Description

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

Product Operation

When de-energized, the SV08-31 allows flow from 2 to 1, while blocking flow at 3. When energized, the valve’s spool shifts to open from 1 to 3, while blocking at 2. While port 1 may be fully pressurized, it is not intended to be used as the inlet.
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.
