4/2 Solenoid Directional Valve
SAE 8-Cartridge – 350 bar
WK08R-01
Spool Type - Direct Acting
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 port 2 to 1 or 1 to 2.
When energized, the valve allows ow
from port 1 to 4 or 4 to 1 while blocking
ow at port 3 and 2.
Function
Features
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
Low pressure drop due to CFD optimized ow-path
