DIRECTIONAL CONTROL VALVE
COMPACT VERSION
MOUNTING SURFACE OPERATING PRINCIPLE
— Direct acting, subplate mounting directional control
valve, with mounting surface according to ISO 4401-03
standards.
— Compact design with reduced solenoid dimensions,
suitable for mini-power packs and mobile and
agricultural applications.
— The valve body is made with high strength iron castings
provided with wide internal passages in order to
minimize the flow pressure drop. Wet armature
solenoids with interchangeable coils are used (for
further information on solenoids see paragraph
7).
— The valve is supplied with 3 or 4 way designs
and with several interchangeable spools with
different porting arrangements.
— The valve is available with DC or AC current
solenoids and with several types of electrical
connections to cover various installation
requirements (see paragraphs 7 and 11).
— The DC valve comes with boot protected
manual override which ensures a protection
degree IP69K for connections types WK7 and
WK8.
— It is available also with zinc-nickel surface
treatment, that ensures a salt spray resistance
up to 600 hours.

- 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.

The curves define the flow rate operating fields according to the valve pressure of the different versions. The values indicated in the graphs are
relevant to the standard solenoid valve.
The operating limits can be considerably reduced if a 4-way valve is used as 3-way valve with port A or B plugged or without flow.
The values have been obtained according to ISO 6403 norm with solenoids at rated temperature and supplied with voltage equal to 90% of the
nominal voltage. The value have been obtained with mineral oil, viscosity 36 cSt, temperature 50 °C and filtration according to ISO 4406:1999
class 18/16/13.

7 - 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, and can be rotated +/- 90°, to suit the available space.
The interchangeability of coils of different voltages is allowed within the same type of supply current, alternating or direct.

Protection from atmospheric agents IEC 60529
The IP protection degree is intended for the whole valve. It is
guaranteed only with both valve and connectors of an equivalent IP
grade, correctly connected and installed.
7.2 - DC valve - Current and power consumption
In direct current energizing, current consumption stays at fairly constant values, essentially determined by Ohm’s law: V = R x I
“R” coils have to be used when the valve is fed with AC power supply subsequently rectified by means of rectifier bridge, externally or
incorporated in the “D” type connector (see cat. 49 000).
The table shows current and power consumption values for DC and RC coil types.

NOTE: In order to further reduce the emissions, with DC supply,

peaks on opening of the coil supply electrical circuit (see cat.

7.3 - AC valve - Current and power consumption
In alternating current energizing, an initial phase (maximum movement) is seen, during which the solenoid consumes elevated value currents
(inrush current); the current values diminish during the plunger stroke until it reaches the minimum values (holding current) when the plunger
reaches the stroke end. The table shows the values of absorption at the inrush and at holding.

10 - INSTALLATION
Configurations with centering and return springs can be mounted in any position; type RK valves
- without springs and with mechanical detent - must be mounted with the longitudinal axis horizontal.
Valve fitting takes place by means of screws or tie rods, fixing the valve on a lapped surface, with
values of planarity and smoothness that are equal to or better than those indicated in the drawing.
If the minimum values of planarity or smoothness are not met, fluid leakages between valve and
mounting surface can easily occur.
