4/2-Solenoid
Directional Valve
SAE 8-Cartridge – 350 bar
WK08A-01
SPOOL Type - Direct Operated
19 l/min
350 bar
In the de-energized mode, the valve
allows ow from port 3 to 4 or 4 to 3
and from 2 to 1 or 1 to 2.
When energized, the valve blocks all
directions.
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
Operating pressure: 350 bar
Nominal ow: 19 l/min
Consult factory for ow ratings
