2/2 Solenoid Directional Valve
Cartridge Valve – 350 bar
SEAT Type - Pilot Operated
Normally Open
WSM06020Y-01
up to 40 l/min
up to 350 bar
When the solenoid coil is not energized,
there is free flow through the valve from
port 2 to port 1. Flow from port 1 to port 2
is severely restricted in this mode.
When the solenoid coil is energized, the
valve is closed from port 2 to port 1.
In the reverse direction there is free flow
through the valve when the pressure
force on the spool exceeds the solenoid
force (approx. 9 to 20 bar).

GENERAL
z Long life and low noise level due to oil-immersed solenoid armature.
z Electro-magnetic actuation available in all standard international DC and AC
voltages and many electrical connection types available.
z Minimal wear and long life due to hardened and polished control elements.
z In the closed position the flow paths are shut off by means of a cone seat.
z Solenoid coils can be rotated through 360° and replaced without opening
the hydraulic system.
z Surfaces are zinc-plated.
z Built-in seals protect solenoid coils from water penetration.
z Compact construction enables space-saving installation in connection housings
and control blocks.
