4/2-Solenoid Directional Valve

SAE 8-Cartridge – 350 bar

WK08P-01

SPOOL Type - Direct Operated

15 l/min

350 bar

In the de-energized mode, the valve

allows ow from 4 to 1, while blocking

2 and 3.

When energized, the valve allows ow

from 3 to 4 or 4 to 3 and from 2 to 1.



 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 by CFD optimized ow-path
