Description
The 3-way/2-position solenoid-operated directional
seat valves, series W1D_B (installation deep), are size
6, direct acting, and pressure balanced screw-in val-
ves. They are designed on the tried and tested prin-
ciple of the guided poppet, and the guide spool has a
seal. This valve type has an underlapped spool. In the
crossover position, all connections are thus connected,
i.e., there is a connection between ports 1, 2, and 3
during the valve’s switching period. 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 available with or
without manual override, and with the option of an
additional hand lever. All external parts of the cartrid-
ge are zinc-nickel plated, and are thus suitable 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 angle through
360°. These valves are predominantly used in certain
mobile and industrial applications where leak-tight
shut-o functions are crucially important. Examples
are where loads, tensions, or clamping forces must be
held without leakage. For self-assembly, please refer
to the section related data sheets.
