E 5.971.1/12.10
428
4/2-Solenoid Directional Valve
SAE 10-Cartridge - 350 bar
WK10Y-01
SPOOL Type - Direct Acting
32 l/min
350 bar
In the de-energised mode, the valve
allows ow bidirectionally between ports
3 and 4 and ports 1 and 2.
When energised, the valve allows ow
bidirectionally between ports 2 and 3
and ports 1 and 4
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
