3/2 solenoid directional valve
Poppet type, Direct-acting
SAE-08 Cartridge – 350 bar
WS08C-01
up to 22 l/min
up to 350 bar
The directional valve WS08C-01 is an
electromagnetically actuated, direct
acting 3/2 poppet valve.
When de-energized, there is free ow
through the valve from port 2 to port 3.
Port 1 is closed. When energized, the
valve allows ow from port 1 to 2, while
blocking ow at port 3.
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
