Solenoid Directional Valve
With Electronic Switch Position
Monitoring
SAE 8-Cartridge - 350 bar
WS08Z-01E
2/2 Normally Closed
Poppet-type - Pilot-Operated
up to 40 l/min
up to 350 bar
When de-energized, the valve is shut-off
from port 2 to port 1.
Flow is permitted in the opposite
direction. The valve piston opens at a
differential pressure of approx. 1.8 bar
(check function).
When energized, the valve allows ow
from port 2 to 1. Return ow from port
1 to 2 is severely restricted. In addition,
this valve has electronic switch position
monitoring.
features
With electronic switch position monitoring
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
No CE approval, do not use to control dangerous actions of machines due to machin-
ery directrive.
