REPRODUCTION IS FORBIDDEN. THE COMPANY RESERVES THE RIGHT TO APPLY ANY MODIFICATIONS.
15 - HYDRAULIC FLUIDS
Use mineral oil-based hydraulic fluids HL or HM type, according to ISO 6743-4. For these fluids, use NBR seals. 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.
16 - INSTALLATION
The valves can be installed in any position without impairing correct
operation. Make sure the hydraulic circuit is free of air.
Valves are fixed by means of screws or tie rods on a flat surface
with planarity and roughness equal to or better than those indicated
in the relative symbols. If minimum values are not observed, fluid
can easily leak between the valve and support surface.
Take care to the cleanliness of the mounting surfaces and
surrounding environment upon installation.

17 - ACCESSORIES
(to be ordered separately)
17.1 - Mating connectors
Mating connectors must be ordered separately. See catalogue 89 000.
We recommend the choice of a metal connector to avoid electromagnetic disturbances and to comply with EMC regulations on
electromagnetic compatibility. If you opt for a plastic connector, make sure that it guarantees and maintains the IP and EMC
protection characteristics of the valve.
17.2 - Mating connectors for fieldbus communication and for sensors.
Duplomatic offers spare parts to be wired and also ready-to-use cord sets. Please refer to cat. 89 000.
17.3 - Connection cable
The optimal wiring provides for 7 isolated conductors, with separate screen for the signal wires (command, monitor) and an overall screen.
Cross section for power supply:
- up to 20 m cable length : 1,0 mm
2
- up to 40 m cable length : 1,5 mm
