OPERATING PRINCIPLE
— The E*P4 piloted valves are constituted of a 4-way
hydraulic operated distributor with a mounting surface in
accordance with the ISO 4401 standards, operated by a
ISO 4401-03 solenoid directional valve.
— They are made in CETOP P05 and ISO 4401-05 sizes
with flow rates up to 150 l/min, and in ISO 4401-08 size
with flow rates up to 600 l/min.
— They are available with different spool types (see par. 2)
and with some options for the opening control.
— They are available with both the solenoid and the
hydraulic control from the X and Y ways.
— A version for high pressures (H) is available.
— It is available also with zinc-nickel surface treatments,
that ensures a salt spray resistance up to 600 hours.

4 - 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 solenoid controlled
distributors, omit for hydraulic controlled). 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.

8.1 - Backpressure valve incorporated on line P available for E5 valve only)
Valve E5 is available upon request with backpressure valve incorporated on line P. This is necessary to obtain the piloting pressure when the
control valve, in the rest position, has the line P connected to the T outlet (spools S2 - S4 - S7 - S8 - TA002 - TC002 - RK002). The cracking
pressure is of 5 bar.
Add C3 to the identification code for this request (see paragraph 1). In the C3 version the piloting is always internal.
E5P4/C3
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
direct check valve because it doesn’t assure the
seal.

9 - ELECTRICAL FEATURES
9.1 - 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 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 catalogue. 49 000).

9.2 - 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%.

10 - OPTIONS
10.1 - Control of the main spool stroke: C
It is possible to introduce special stroke controls in the heads of the hydraulic pilot
operated 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).
10.2 - Control of the main spool shifting speed: D
By placing a MERS type double flow control valve between the pilot solenoid valve
and the hydraulic operated valve, 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).
10.3 - 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 PF to the identification code to request this option (see paragraph 1).
10.4 - Control of the main spool stroke and shifting speed: G
It is possible to have the valve fitted with both the spool stroke device and the piloting
flow rate control device.
Add the letter G to the identification code to request this solution (see paragraph 1).

11 - INSTALLATION
Configurations with centering 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 class 10.9 fastening screws is recommended for valves in version H
(high pressure).
