2/2 Directional Poppet Valve
Solenoid-Operated, Direct
Acting, Normally Closed
Metric Cartridge – 350 bar
WSM06020W-61
Up to 25 l/min
Up to 350 bar
The WSM06020W-61 is the high
performance version of the standard
WSM06020W-01. Thanks to its larger
coil and modied design, the valve
switches up to 350 bar and permits a
ow rate of 25 l/min.
When the solenoid is not energized, the
valve is closed in both directions. When
the solenoid is energized, the valve
allows ow in both directions.
Caution: No orice is to be placed just
before port 1.
Features
z High performance version for high pressures and long service life
z All exposed surfaces zinc-plated and corrosion-proof
z All valve parts made of high-strength steel with hardened and ground components
to ensure minimal wear and extended service life
z Solenoid seals protect the solenoid system
z Wide variety of connectors available
z Excellent switching performance by high power HYDAC solenoid
z Low pressure drop due to CFD optimized ow-path
