2/2 Solenoid Directional Valve
Metric Cartridge – 350 bar
Normally Closed
WSM12120W
Poppet Type - Pilot Operated
up to 110 l/min
up to 350 bar
When the solenoid coil is not energized,
the valve is closed in both directions.
When the solenoid coil is energized,
there is free ow through the valve in
both directions.
Exposed 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
Coil seals protect the solenoid system
Wide variety of coils and connectors available
Excellent switching performance by high power HYDAC solenoid
