When de-energized, the ISV08-33 allows flow from ③ to ①, while blocking flow at ②. When energized, the cartridge's spool shifts to open the ② to ① flow path, while blocking flow at ③.
To override, push button in, twist counterclockwise 180°, and release. 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 operation, push button in, twist clockwise 180°, and release. Override will be detented in this position.
