E 5.998.2.0/12.10

Solenoid Directional Valve
SAE 12-Cartridge - 350 bar
2/2 Normally Open
WS12Y-01
Poppet Type - Pilot Operated
110 l/min
350 bar
In the de-energized mode, the valve
allows ow from 2 to 1. Flow from 1 to 2
is severely restricted in this mode.
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
(1.5 to 6.5 bar).
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 by 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
