4/3 Solenoid Directional Valve
SAE 10-Cartridge – 350 bar
Tandem Center
WK10G-01
Spool Type - Direct Acting
23 l/min
350 bar
In the de-energized mode, the valve
blocks ports 2 and 4, while allowing ow
from port 3 to 1.
When coil S1 is energized, ow is
allowed from port 3 to 2 and from 4 to 1.
When coil S2 is energized, ow is
allowed from port 3 to 4 and from 2 to 1.
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
Operating pressure: 350 bar
Nominal ow: 23 l/min
