E 5.995.0/12.10
414
3/2-Solenoid Directional Valve
SAE 10-Cartridge - 350 bar
Special low pressure drop design
WK10C-40
SPOOL Type - Direct Operated
32 l/min
350 bar
In the de-energized mode, the valve
allows ow from 2 to 1 or from 1 to 2,
while blocking ow at 3.
When energized, the valve allows ow
from 3 to 2 or from 2 to 3, while blocking
ow at 1.
FEATURES
Excellent switching performance by high power HYDAC solenoid
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and to extend service life
Rigid design using one-piece body minimizes the effect of eccentricity and
maximizes reliability
All surfaces zinc-plated and corrosion-proof
Waterproof design standard
Wide variety of connectors available
Low pressure drop by CFD optimized ow-path
