SHUT-OFF VALVES

POSITION MONITORING

SERIES 10

MOUNTING INTERFACE OPERATING PRINCIPLE

— M*F3 are shut-off valves, solenoid or hydraulically

actuated, with or without spool position monitoring, in

modular version, with mounting interface according to

ISO 4401-03 standard.

— M*F3 valves are placed under directional control

servovalves in order to guarantee the safety of circuit

when a power failure occurs.

— Spools with float, closed, parallel or cross position in de-

energized condition are available.

— Versions with spool monitoring do not have

manual override and can not be disass-

embled, because of their characteristics and

their possible use on machinery subject to

safety requirements.

— The spool position monitoring is available

either for initial position or for actuated

position.

3 - 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 fluid types 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.

7 - MDF3 - ELECTRICAL FEATURES

7.1 - 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; versions without

the spool monitoring and can be rotated, to suit the available space.

NOTE 1: In order to further reduce the emissions, use of type H

connectors is recommended. These prevent voltage peaks on

opening of the coil supply electrical circuit (see cat. 49 000).

NOTE 2: The IP65 protection degree is guaranteed only with the

connector correctly connected and installed.

7.2 - Current and absorbed power

The table shows current and power consumption values relevant to

the different coil types for DC.

Using connectors type "D" (see cat. 49 000) with embedded bridge

rectifier it is possible to feed DC coils (starting from 48V voltage)

with alternating current (50 or 60 Hz), considering a reduction of the

operating limits of about 5-10%.
