— BDL, BDM and BDS are stacked valve assemblies, very
well-rounded thanks to their modular design.
— Elements have been designed to be assembled in parallel
connection, mounting up to 10 stackable valves. The same
elements allow to create series circuits by inserting plugs in
order to divert the oil path.
— Elements specifically designed for BD*2 series circuits
complete the BD* range.
— BD* assemblies are suitable for compact applications in the
mobile and in mini-power pack industries.
— Directional valve elements are available in two thicknesses,
with working ports 3/8” BSP, 1/2” BSP, SAE–06 and
SAE–08 threaded.

2 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals (code N). For fluids HFDR type
(phosphate esters) use FPM seals (code V). For the use of other kinds of fluid such as HFA, HFB, HFC, please consult our technical
department.
Using fluids at temperatures higher than 80 °C causes a faster degradation of the fluid and of the seals characteristics.The fluid must be
preserved in its physical and chemical characteristics.

6 - ELECTRICAL FEATURES
6.1 - Solenoids
These are essentially made up of two parts: tube and coil. The tube
is threaded into the valve body and includes the armature that
moves immersed in oil, without wear. The inner part, in contact with
the oil in the return line, ensures heat dissipation. The coil is
fastened to the tube by a threaded ring, and can be rotated to suit
the available space.
6.2 - Protection from atmospheric agents IEC 60529
The IP protection degree is guaranteed only with both valve and
connectors of an equivalent IP degree, correctly connected and
installed.
The protection degree IP69K is not taken into account in IEC 60529
but it is included in ISO 20653.

Coils with letter ‘W’ feature a zinc-nickel surface treatment, that makes them resistant to exposure to the salt spray for 600 hours (test
performed according to UNI EN ISO 9227 and assessment test performed according to UNI EN ISO 10289).
The WK7D coils include a suppressor diode of pulses for protection from voltage peaks during switching. During the switching the diode
significantly reduces the energy released by the winding, by limiting the voltage to 31.4V in the D12 coils and to 58.9 V in the D24 coils.

14 - IDENTIFICATION CODES OF SEPARATE ELEMENTS FOR BDL2 AND BDM2 SERIES CIRCUITS
14.1 - Directional valve element
This code identifies BD*2 elements, designed for series connection. Series circuits with BD*3 modules are feasible by inserting plugs to divert
the oil path (see paragraph 13.2).
NOTE: if no unloading valve is needed,
the identification code ends with seals digit.
Example: BD3-B38S-S140-Q/10N
Material:
S = Steel (standard)
