2/2 Solenoid Directional Valve
Cartridge Valve – 350 bar
SEAT Type - Pilot Operated
Normally Closed
WSM06020Z-01
up to 40 l/min
up to 350 bar
When the solenoid coil is not energized,
the valve is closed from port 2 to port 1.
In the reverse direction there is free
ow through the valve. The valve spool
opens at a differential pressure of
approx. 1.5 bar (check function).
When the solenoid coil is energized,
there is free ow through the valve from
port 2 to port 1. Flow from port 1 to
port 2 is severely restricted in this mode.

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