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 with higher pressures it is necessary to use the version with external pilot and reduced pressure. Otherwise, the

valve with internal pilot and pressure reducing valve with 30 bar fixed adjustment can be ordered.

Add the letter Z to the identification code to order this option (see par. 4.1). Consider that, by adding the pressure reducing valve, the overall

7.1 - Backpressure valve incorporated on line P (C option)

DSP7K* and DSP8K* valves 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 - S*2 - S*4 - T*02). The cracking pressure is of 5 bar with a minimum flow rate of

15 l/min.

In the C version the piloting is always internal.

NOTE: the backpressure valve can’t be used as check valve because it doesn’t assure the seal.

Add C to the identification code for this request (see paragraph 4.1).

For DSP7K* only, the backpressure valve can be also delivered separately and it can be easily mounted on line P of the main control valve.

Ask for code 0266577 to order the backpressure valve.

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).

8.1 - Wiring

In order to realise the electrical connection of the coil, it is necessary to access the terminal block (1) unscrewing the 4 screws (2) that fasten

the cover (3) with the box (4) that contains the terminal block.

The electrical connection is polarity-independent.

By doing electrical connection it is important to connect also the grounding point (5) in the terminal block box (M4 screws), through suitable

conductors with the general grounding line of the system.

On the external body of the coil there is a grounding point (6) (M4 screw) that allow to ensure equipotentiality between the valve and the

general grounding line of the system; connecting this point the regulation of the EN 13463-1 standard, that impose to verify the equipotentiality

of the elements included in a potentially explosive environment (the maximum resistance between the elements must be 100 Ω), is

guaranteed.

At the end of the electrical wiring, it is necessary to reassemble the cover (3) on the box (4), checking the correct positioning of the seal located

in the cover seat and fastening the 4 M5 screws with a torque of 4.9 ÷ 6 Nm.

Electrical wiring must be done following in compliance with standards about protection against explosion hazards.

8.3 - Overcurrent fuse and switch-off voltage peak

Upstream of each valve, an appropriate fuse (max 3 x In according to IEC 60127) or a protective motor switch with short-circuit and thermal

instantaneous tripping, as short-circuit protection, must be connected. The cut-off power of the fuse must correspond or exceed the short circuit

current of the supply source. The fuse or the protective motor must be placed outside the dangerous area or they must be protected with an

explosion-proof covering.

In order to safeguard the electronic device to which the valve is connected, there is a protection circuit in the coil, that reduces voltage peaks,

which can occur when inductances are switched off.

The table shows the type of fuse recommended according to the nominal voltage of the valve and to the value of the voltage peaks reduction.

9 - OPTIONS

9.1 - 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 4.1).

9.2 - 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 4.1).

9.3 - Subplate with throttle on line P

It is possible to introduce a subplate with a restrictor on line P

between the pilot solenoid valve and the main distributor.

16 - 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.

17 - INSTALLATION

Installation must adheres to instructions reported in the Use and Maintenance manual,

always attached to the valve. Unauthorized interventions can be harmful to people and

goods because of the explosion hazards present in potentially explosive atmospheres.

Configurations with centering and recall springs can be mounted in any position; The RK versions,

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.

18 - MANUAL OVERRIDES

18.1 - CB - Blind ring nut

The metal ring nut protects the solenoid tube from atmospheric

agents and isolates the manual override from accidental operations.

The ring nut is tightened on a threaded fastener that keeps the coil

in its position even without the ring nut.

To access the manual override loosen the ring nut and remove it;

then reassemble hand tightening, until it stops.

Activate the manual override always and only with non-

sparking tools suitable for use in potentially explosive

atmospheres.

More information on safe use of explosion-proof components are

provided in the instruction manual, always supplied with the valve.

18.2 - CK - Knob manual override

When the set screw is screwed and its point is aligned with the edge

of the knob, tighten the knob till it touches the spool: in this position

the override is not engaged and the valve is de-energized. After

adjusting the override, tighten the set screw in order to avoid the

knob loosing. Available for DC valves only.

Spanner: 3 mm

18.3 - CH - Lever manual override

The lever manual override is available for DSE3K only. The seals

choice leads the type of the standard ring nut to be mounted.

The lever device is always placed at side A.

1.3 - ATEX classification of the coils

The coil of the explosion-proof valves is ATEX certified itself an as such is identified with its own tag, carries the relative ATEX marking.

The mechanical construction of the coil housing is made in order to ensure its resistance to possible internal explosion and to avoid any

explosion propagation to the outside environment, matching an “Ex d” type protection (explosion-proof coil).

Moreover, the solenoid is designed to maintain its surface temperature below the limits specified to the relevant class.

2 - IECEx CLASSIFICATION AND TEMPERATURES

The IECEx certification requires the classification of the electrical equipment only.

Duplomatic supplies valves with IECEx certified coils, suitable for application and installation in potentially explosive atmospheres. The

mechanical construction of the coil housing is made in order to ensure its resistance to possible internal explosion and to avoid any explosion

propagation to the outside environment, matching an “Ex db” type protection (explosion-proof coil).

Moreover, the solenoid is designed to maintain its surface temperature below the limits specified to the relevant class.

The supply always includes the operating and maintenance manual, that contains all the information needed for a correct use of the valve in

potentially explosive environment.

2.1 - IECEx classification

Certificate of conformity (CoC): IECEx TUN 15.0028X

The valves are suitable for applications and installations in potentially explosive atmospheres that fall within:
