3/2-Solenoid Directional Valve
SAE 8-Cartridge - 350 bar
WK08D-01
SPOOL Type - Direct Operated
19 l/min
350 bar
In the de-energized mode, the valve
allows ow bidirectionally between ports
2 & 3, while blocking ow at 1.
When energized, the valve allows ow
bidirectionally between ports 1 & 2, while
blocking ow at 3.

All surfaces zinc-plated and corrosion-proof
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and extended service life
Coil seals protect the solenoid system
Wide variety of connectors available
Rigid design using one-piece body minimizes the effect of eccentricities in cavity
and maximizes reliability
Excellent switching performance by high power HYDAC solenoid
Low pressure drop due to CFD optimized ow-path
