4/2-Solenoid
Directional Valve
SAE 8-Cartridge - 350 bar
WK08Y-01
SPOOL Type - Direct Operated
19 l/min
350 bar
In the de-energized mode, the valve
allows ow bidirectionally between ports
3 and 4 and between ports 1 and 2.
When energized, the valve allows ow
bidirectionally between ports 2 and 3
and between ports 1 and 4.
