Description
The 3-way/2-position solenoid-operated directional
seat valves, series W1F_B (installation deep), are size
6, direct acting, and pressure balanced screw-in valves.
They are designed on the tried and tested principle of
the guided poppet, and the guide spool has a seal.
This valve type has an overlapped spool. In the cros-
sover position, all connections are thus disconnected,
i.e., there is no connection between ports 1, 2, and 3
during the valve’s switching period, with the result that
only a minimal loss of the ow/pressure occurs. This
type is the "deep" installation version, which ts into
the cavity type according to the AD factory standard.
For the "shallow" installation version, see separate
data sheet. These cartridge seat valves are also avai-
lable with or without manual override, and with the
option of an additional hand lever. All external parts of
the cartridge are zinc-nickel plated, and are thus sui-
table for use in the harshest operating environments.
The slip-on coils can be replaced without opening the
hydraulic envelope and can be positioned at any ang-
le through 360°. These valves are predominantly used
in certain mobile and industrial applications where le-
ak-tight shut-o functions are crucially important. Ex-
amples are where loads, tensions, or clamping forces
must be held without leakage. For self-assembly, plea-
se 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".

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.

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.
IMPORTANT!
Hand levers can only be tted to valves that
have a manual override.
