4/2-Solenoid Directional
Valve SAE 8-Cartridge – 350 bar
WK08X-01
SPOOL Type - Direct Operated
17 l/min
350 bar
In the de-energized mode, the valve
allows ow bidirectionally between ports
2 and 3 and ports 1 and 4.
When energized, the valve allows ow
bidirectionally between ports 3 and 4
and ports 1 and 2.

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
