DASV08-40 Spool, 3-Way

DESCRIPTION

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

OPERATION

When de-energized，DASV08-40 flow paths are 3 to 2 , and 4 to 1 .When energized,the valve’s spool shifts to open 3 to 4 , and 2
to 1 . All ports are open at cross-over. Operation of Manual Override Option: To override, push button in and twist counterclockwise180° . 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.
