2/2 Solenoid Directional Valve
Cartridge Valve - 350 bar
SEAT Type – Pilot Operated
Normally Open (Reverse Flow)
WSM06020YR-01
up to 40 l/min
up to 350 bar
When the solenoid coil is not energized,
there is free ow through the valve in
both directions.
When the solenoid coil is energized, the
valve is closed from port 2 to port 1.
In the reverse direction there is free ow
through the valve when the pressure
force on the spool exceeds the solenoid
force (approx. 9 to 20 bar).
GENERAL
Excellent switching performance by high power HYDAC solenoid
All valve parts made of high-strength steel with hardened and ground compon-
ents to ensure minimal wear and extended service life
Rigid design by one-piece-body minimizes the effect of eccentricity and maximi-
zes reliability
All surfaces zinc-plated and corrosion-proof
Waterproof design standard
Wide variety of connectors available
Low pressure drop by CFD optimized ow-path
