E 5.960.1/12.10
444
4/2-Solenoid Directional Valve
SAE 10-Cartridge - 350 bar
WK10Z-01
SPOOL Type - Direct Operated
32 l/min
350 bar
In the de-energized mode, the valve
blocks ow in all directions.
When energized, the valve allows ow
from 3 to 4 or 4 to 3 and from 2 to 1 or
1 to 2.
Features
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
