3/2-Solenoid Directional Valve

SAE 10-Cartridge - 350 bar

WK10L-01

SPOOL Type - Direct Operated

32 l/min

350 bar

In the de-energized mode, the valve

allows ow from port 1 to 2 or from 2 to

1, while blocking ow at 3.

When energized, the valve allows ow

from port 3 to 1 or from 1 to 3, while

blocking ow at 2.

Function

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
