E 5.906.1.0/12.10
410
3/2-Solenoid Directional Valve
SAE 8-Cartridge – 350 bar
WK08C-13
Spool Type - Direct Acting
19 l/min
350 bar
In the de-energized mode the valve
allows ow from port 2 to 1 and not in
the other direction, while blocking ow at
port 3.
When energized the valve allows ow
from port 3 to 2 or from 2 to 3, while
blocking ow at port 1.
Function
Features
Δp optimized, for optimized pressure drop from port 2 to1
Exposed 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 coils and connectors available
Excellent switching performance by high power HYDAC solenoid
