E 5.946.2.0/12.10
308
2/2 Solenoid Directional Valve
Poppet Type - Pilot Operated
Spring-Return Manual Override
Normally Closed (Reverse Flow)
Cartridge Valve - 350 bar
WSM06020ZR-01J
In the de-energized mode, the valve
blocks ow from 2 to 1 and acts as a
check allowing ow from 1 to 2.
When energized, the valve allows ow in
both directions.
Features
All surfaces zinc-plated and corrosion-proof.
Minimal wear and extended service life due to hardened and ground valve
components.
Waterproof design as standard.
Wide variety of connectors available.
Rigid design using one-piece body minimises the effect of eccentricity and
maximises reliability.
Excellent switching performance by high power HYDAC solenoid.
Low pressure drop due to CFD optimised ow-path.
