Solenoid Directional Valve
SAE 8-Cartridge - 350 bar
2/2-Normally Closed (Reverse Flow)
WS08ZR-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 port 1 to 2.
When energized, the valve allows ow in
both directions.
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
Operating pressure: 350 bar
Nominal ow: 38 l/min
Internal leakage: leakage free (less than 5 drops/min)
max. at 350 bar
Media operating temp. range: - 20 °C to + 120 °C
