MODULAR SUBPLATES

FOR ISO 4401-03

VALVES

Q max 50 l/min

This series of modular subplates has been designed to make

hydraulic circuits and can be used directly on power packs or on

any other section of the machine.

The subplates are assembled by means of 4 tie-rods with seal seats

incorporated in the subplate.

The above assembly achieves compact units (including pressure

and discharge manifolds): one face per subplate is used for

connection to services and the other to mount ISO 4401-03 valves.

Complex circuits can also be set up using modular valves.

The recommended mounting configuration for P2* subplates on

hydraulic power packs is with the main axis positioned vertically to

obtain the bundle of pipes to utilities in two vertical rows; however

assembly is not restricted to this configuration.

10 - 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.

11 - PRESSURE LIMIT ON P

Depending on the tie-rod type and on the number of assembled subplates it is necessary to pay attention to the maximum pressure on P in

order to avoid extruding the O-Rings.
