Solenoid Directional Valve
SAE 8-Cartridge - 350 bar
2/2-Normally Open (Reverse Flow)
WS08YR-01
Poppet Type - Pilot Operated
38 l/min
350 bar
In the de-energized mode, the valve
allows ow in both directions.
When energized, the valve blocks ow
from port 2 to 1. In this mode the valve
will allow ow from port 1 to 2 after the
hydraulic force overcomes the solenoid
force of 9 to 20 bar.

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
