Description
The 2-way/2-position solenoid operated directional
seat valves, series W1C_B (shallow), are size 6, direct
acting, pressure balanced, push-in valves. They are de-
signed on the poppet/seat principle and are leak-tight
in both ow directions (bidirectional seat-valve shut-
o). The guide spool has a seal. This version is the
mounting version "shallow" which ts into the cavity
AA according to factory standard. See separate data
sheet for the mounting version "deep". These valves
are also available with or without manual override,
and with the option of an additional hand lever. All ex-
ternal parts of the screw-in valves are zinc-nickel pla-
ted and are thus suitable for use in the harshest ope-
rating environments. The slip-on coils can be replaced
without opening the hydraulic envelope and can be
positioned at any angle through 360°. These valves
are predominantly used in certain mobile and indus-
trial applications where leak-tight shut-o functions
are crucially important. Examples are where loads,
tensions, or clamping forces must be held without le-
akage. For self-assembly, please refer to the section
related data sheets.

IMPORTANT!
To ensure the performance data is not com-
promised, it is imperative to use coils D45/207
according to data sheet 400-P-120120.
NOTE!
These times are strongly inuenced by
uid pressure, ow rate and viscosity, as
well as by the dwell time under pressure.

Installation information
ATTENTION!
Only qualied personnel with mechanical
skills may carry out any maintenance work.
Generally, the only work that should ever be
undertaken is to check, and possibly replace,
the seals. When changing seals, oil or grease
the new seals thoroughly before tting them.
NOTE!
1) When tting the slip-in valves, use
the specied tightening torque for the
mounting screws. The value can be
found in the chapter "Technical data".

Reference: 400-P-110111-EN-01/03.2023
IMPORTANT!
When replacing an old coil with connection
according to DIN 43650/ISO4400 (with other
Pin setup than according to datasheet 400-P-
120120), the new coil can be mounted in 180°
reversed position so that the existing plug
(with 180° earthingPIN) can be connected.
This does not aect the performance data.
IMPORTANT!
A “de-energized open” function can be crea-
ted by using the 3/2 solenoid cartridge val-
ve and the GADA line-mounting body. In this
case, ports 2 and 3 are used. Port 1 is plugged.

As an option, these valves are available with an addi-
tional hand lever. The hand lever can be tted on the
solenoid. Two models can be supplied:“HHB” hand le-
ver with detent feature, and the “HHNB” hand lever
without detent feature.
NOTE!
These valves can also be tted in the cavity AC
according to factory standard, and in such ca-
ses port 3 then has the same function as port 2.
IMPORTANT!
Hand levers can only be tted to valves that
have a manual override.
