Solenoid Directional Valve
SAE 8-Cartridge - 250 bar
2/2 Normally Closed (double blocking)
Screen Filter
WS08W-30
Poppet Type - Direct Operated
20 l/min
250 bar
In the de-energized mode, the valve
blocks ow in both directions.
When energized, the valve allows ow in
both directions.
FEATURES
Excellent switching performance by high power HYDAC solenoid
All valve parts made of high-strength steel with hardened and ground
components to ensure minimal wear and to extend service life
Rigid design using one-piece body minimizes the effect of eccentricity and
maximizes reliability
All surfaces zinc-plated and corrosion-proof
Waterproof design standard
Wide variety of connectors available
Low pressure drop by CFD optimized ow-path
In ow direction 2 to 1 internal valve parts protected against coarse contaminant
particles by screen lter
