2/2 Solenoid Directional Valve
Poppet Type - Pilot Operated
Normally Open
Cartridge Valve – 350 bar
WSM10120Y-01

All surfaces zinc-plated and corrosion-proof.
All valve parts made of high-strength steel with hardened and ground compon-
ents to ensure minimal wear and extended service life.
Waterproof design as standard.
Wide variety of connectors available.
Rigid design using one-piece body minimises the effect of eccentricity and maxi-
mises reliability.
Excellent switching performance by high power HYDAC solenoid.
Low pressure drop due to CFD optimised ow-path.

Operating pressure: max. 350 bar
Nominal Flow: max. 75 l/min
Internal leakage: leakage-free
Media operating temp. range: -20 °C to +120 °C
Ambient temperature range: -20 °C to +60 °C
Type of voltage: DC solenoid, AC voltage is rectied
using a bridge rectier built into the coil
Current draw at 20 °C: 1.5 A at 12 V DC
0.8 A at 24 V DC
Voltage tolerance: ±15% of nominal voltage
Coil duty rating: Continuous up to 115 % of niminal
voltage at 60 °C ambient temperature
Response time: Energized: approx. 60 ms
De-energized: approx. 20 ms
Fluids: Hydraulic oil to DIN 51524 Part 1 and 2
Viscosity: 10 mm²/s to 420 mm²/s is recommended
Filtration: Permissible contamination level
of the operating uid to ISO 4406
Class 21/19/16 or cleaner
Installation: No orientation restrictions
Materials: Valve body: high tensile steel
Closing elements: hardened and
ground steel
Seals: NBR (standard)
FKM (optional)
back-up ring
in PTFE
Coil: Steel/Polyamide
Cavity: 10120
Weights: Valve complete: 0.370 kg
Coil only: 0.190 kg
up to 75 l/min
up to 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 of
2.5 to 10 bar.
