E .0/12.10
354
2/2 Solenoid Directional Valve
Poppet Type - Pilot Operated
Normally Open (Reverse Flow)
Cartridge Valve - 350 bar
WSM10120YR-01
In the de-energized mode, the valve
allows ow in both directions.
When energized, the valve blocks ow
from 2 to 1. In this mode the valve will
allow ow from 1 to 2 after the hydraulic
force overcomes the solenoid force of
2.5 to 10 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
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
Operating pressure: Max. 350 bar
