2/2 Solenoid Directional Valve
Poppet Type - Pilot Operated
Normally Closed (Reverse Flow)
Cartridge Valve - 350 bar
WSM10120ZR-01
In the de-energized mode, the valve
blocks ow from 2 to 1 and acts as a
check allowing the ow from 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
Waterproof design standard
Wide variety of connectors available
Rigid design using one-piece body minimizes the effect of eccentricity and
maximizes reliability
Excellent switching performance by high power HYDAC solenoid
Low pressure drop by CFD optimized ow-path
