(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.

8 - PERFORMANCE CHARACTERISTICS
NOTE 1 minimum piloting pressure can be the lower range value at low flows rates, but with higher flow rates the higher value is needed.
NOTE 2 If the valve operates at higher pressures it is necessary to use the version with external pilot and reduced pressure. Otherwise, the
valve can be ordered with internal pilot and pressure reducing valve with 30 bar fixed adjustment (pilot type Z, see identification code)
7 - OPERATING LIMITS
The curves define the flow rate operating fields according to the valve pressure for the different spool types.
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 values have been obtained with mineral oil, viscosity 36 cSt at 50 °C, and filtration ISO 4406:1999 class 18/16/13.

9 - PILOTING AND DRAINAGE
The DSP7 valves are available with piloting and drainage, both internal and external. The version with external drainage allows for a higher
back pressure on the outlet.
X: plug M6x8 for external pilot
Y: plug M6x8 for external drain
pilot always internal
Y: plug M6x8 for external drain
9.1 - Backpressure valve incorporated on line P
Valves DSP7 are available upon request with backpressure valve incorporated on line P. This is necessary to obtain the piloting pressure when
the control valve, in rest position, has the line P connected to the T port (spools S2, S4, S7, S8, S*2, S*4, TA02, TB02, RK02). The cracking
pressure is of 5 bar with a minimum flow rate of 15 l/min.
Add C to the identification code for this request (see paragraph 1).
In the C version the piloting is always internal.
The backpressure valve can be also delivered separately and it can be easily mounted on line P of the main control valve. Specify the code
0266577 to order the backpressure valve separately.
DSP7-C
The curve refers to the pressure drop (body part
only) with backpressure valve energized to which
the pressure drop of the reference spool must be
added. (see paragraph 5)
NOTE: the backpressure valve can’t be used as
check valve because it doesn’t assure the seal.

10 - ELECTRICAL FEATURES
10.1 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 360°, to suit the available space.
NOTE: 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 data sheet 49 000).
10.2 - DC coils
In direct current energizing, current consumption stays at fairly constant values, essentially determined by Ohm’s law: V = R x I.
The WK1 and WK7D are coils specific for the high corrosion resistance version of the valve.
The WK7D coil includes 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 coil and to 58.9 V in the D24 coil.
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 by approximately 5 ÷ 10%.
The table shows current and power consumption values for DC coils.

11 - OPTIONS
11.1 - Control of the main spool stroke: C
With the help of special side plugs, it is possible to introduce stroke controls in the
heads of the piloted valve so as to vary the maximum spool clearance opening.
This solution allows control of the flow rate from the pump to the actuator and from
the actuator to the outlet, obtaining a double adjustable control on the actuator.
Add the letter C to the identification code to request this device (see paragraph 1).
11.2 - Control of the main spool shifting speed: D
By placing a MERS type double flow control valve between the pilot solenoid valve
and the main distributor, the piloted flow rate can be controlled and therefore the
changeover smoothness can be varied.
Add the letter D to the identification code to request this device (see paragraph 1).
11.3 - Subplate with throttle on line P
It is possible to introduce a subplate with a restrictor of Ø0,8 on line P between the
pilot solenoid valve and the main distributor.
Add P08 to the identification code to request this option (see paragraph 1).
11.4 - Solenoid operated distributor with pilot valve in configuration S2
It is possible to deliver the solenoid operated distributor with pilot valve in
configuration S2 (all the ports at outlet). With this option the piloting is necessarily
external.
Add S2 to the identification code to request this option (see paragraph 1).
This configuration is used with external piloting in order to allow the unloading of the
piloting line when the solenoid operated valve is in rest position.

14 - INSTALLATION
Configurations with centring and recall 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 fastening takes place by means of screws or tie rods, laying 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.
NOTE: Use of fastening screws class 10.9 is recommended for valves in version H (high pressure).
