Solenoid Directional Valve
SAE 8-Cartridge - 350 bar
2/2-Normally Closed
WS08Z-01
Poppet Type - Pilot Operated
38 l/min
350 bar
In the de-energized mode, the valve
blocks ow from port 2 to 1 and acts as
a check allowing ow from 1 to 2.
When energized, the valve allows ow
from port 2 to 1.
Flow from 1 to 2 is severely restricted in
this mode.
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 coils and 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
