2/2 Solenoid Directional Valve

Poppet Type, Direct Acting,

Normally Closed

Metric Cartridge – 350 bar

WSM10120W-01

up to 40 l/min

up to 350 bar

When the solenoid is de-energized,

the valve blocks ow in both directions.

When energized the valve allows ow in

both directions.

FEATURES

z External surfaces zinc-plated and corrosion-proof

z Hardened and ground internal valve components to ensure minimal wear and

extended service life

z Coil 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
