4/2-Solenoid Directional Valve
SAE 10-Cartridge – 350 bar
WK10N-01
SPOOL Type - Direct Operated
32 l/min
350 bar
In the de-energized mode, the valve
allows ow from port 3 to 1 or 1 to 3
while blocking 2 and 4.
When energized, the valve allows ow
from port 3 to 4 or 4 to 3 and from 2 to 1
or 1 to 2.
Function
Features
z All surfaces zinc-plated and corrosion-proof
z All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and extended service life
z Coil seals protect the solenoid system
z Wide variety of connectors available
z Rigid design using one-piece body minimizes the effect of eccentricities in cavity
and maximizes reliability
z Excellent switching performance by high power HYDAC solenoid
z Low pressure drop due to CFD optimized ow-path
