2/2-Solenoid Directional Valve
SAE 10-Cartridge - 350 bar
WK10W-01
SPOOL Type - Direct Operated
35 l/min
350 bar
This is a bidirectional spool valve in the
de-energized mode.
When energized, the valve allows ow in
both directions.
FEATURES
All 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 connectors available
Rigid design using one-piece body minimizes the effect of eccentricities in cavity
and maximizes reliability
Excellent switching performance by high power HYDAC solenoid
Low pressure drop due to CFD optimized ow-path
