Cartridge Valve - 350 bar
WKM08130D-01
Up to 25 l/min
Up to 350 bar
When the solenoid coil is not energized,
there is free ow through the valve from
port 3 to 2 or from 2 to 3, while port 1 is
closed.
When the solenoid coil is energized,
there is free ow through the valve from
port 2 to 1 or from 1 to 2, while port 3 is
closed.
GENERAL
Oil-immersed armature for long life and low noise operation.
Solenoid operation for all common international AC and DC voltages and
available with many electrical connection types.
Minimal wear and long life due to hardened and polished control spool.
Solenoid coils can be rotated through 360° and replaced with no possibility of
oil leakage.
Surfaces are zinc-plated.
Built-in seals protect solenoid coil from water penetration.
Compact construction enables space-saving installation in connection housings
and control blocks.
