Cartridge Valve - 350 bar
WKM08140X-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, and also from
port 4 to 1 and from 1 to 4.
When the solenoid coil is energized,
there is free ow through the valve from
port 3 to 4 or from 4 to 3 and also from
port 2 to 1 or from 1 to 2.
GENERAL
Oil-immersed solenoid 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.
