Glossary of technical terms used
›A hydraulic mechanism is one in which energy is transmitted via the pressure energy of the working fluid.
›A hydraulic directional control valve is a valve designed to control the direction of movement or stop the output component of an appliance.
›The volumetric flow rate Q is the amount of liquid in volume units that flows through a given flow cross-section per unit time (SI unit is
m3s-1, in practice the unit l/min is used)
›The control solenoid is designed to reposition the valve spool that interconnects or closes the ports in the body. The solenoid consists of
an excitation coil which, by passing an electric current through the winding, generates a magnetic field which exerts a force on the armature of
the mechanical actuating system.
›Pressure is the force acting per area unit (SI unit Pascal (1 Pa = Nm-2), in practice the unit used is bar (1bar = 0.1MPa)
1. Use of the product
The RPER2X3-06 directional control valve is a directly controlled, solenoid operated spool valve. The valve body has a connection pattern at the
base with a nominal clearance of DN 06 according to ISO 4401. The product is designed to control the movement direction of the hydraulic cylinder
piston rod or the rotation direction of the hydraulic motor output shaft by connecting the individual channels via a spool in the valve body. By
stemming the fluid flow through the valve spool, the movement of the appliance can be stopped.
The valve also has a auxiliary manual lever operated emergency spool control that can be used up to 100 bar in the T-port.
Valves with ATEX certification according to Directive 2014/34/EU and IECEx certification according to IECEx OD 009 and related harmonized
standards may be used in explosive atmospheres consisting of firedamp, gas or dust. The valves are marked with the CE Ex mark of conformity and
are accompanied by a Declaration of Conformity.
Use in explosive atmospheres

The valve has a high level of safety (EPL = Mb), which makes initiation unlikely during the interval between gas discharge and valve shutdown.
It is designed for category M2 devices that remain off after gas discharge.
Equipment - group II, where the explosive atmosphere consists of gasses other than mines gas.
The valve has a high level of safety (EPL = Gb) which allows the valve to be used in zones 1 and 2. The valve must not be used in zone 0.
There is a risk of explosion. The valve is certified for gas groups IIA (typical gas is propane), IIB (typical gas is ethylene) also for hydrogen from group IIC.
The joint dimensions do not meet the requirements for Group IIC acetylene.
Equipment - group III, where the explosive atmosphere consists of dust and flammable flying particles.
The valve has a high level of safety (EPL = Db) which allows the valve to be used in zones 21 and 22. The valve must not be used in zone 20. There is
a risk of explosion. The valve is certified for all dust groups - IIIA (flammable flying particles), IIIB (non-conductive dust) and IIIC (conductive dust).

2. Valve protection against initiation of explosion of explosive atmosphere
2.1 Protection of electrical parts
The electrical part of the valve is an ATEX and IECEx certified solenoid coil.
The basic is the „d“ protection by flameproof enclosure (EN 60079-1, IEC 60079-1), which prevents the penetration of hot gases into the surroun-
ding explosive atmosphere in the event that an explosion is initiated inside the flameproof enclosure. For explosive atmospheres consisting of dust,
the enclosure „t“ (EN 60079-31, IEC 60079-31) is used. In addition, the coil is sealed with a potting compound.

3. Risks and limitations of product use
3.1 Risks associated with operating in explosive atmospheres
3.2 Risk associated with the hydraulic part of the valve
DANGER
Explosive atmosphere type and zone
The valve must not be used outside the specified range (see paragraph 1Product use ), in particular it is not
intended for equipment category M1group l (mines) zone 0 group II (gases) and zone 20 group III (dust).
Risk of explosion.
DANGER
Surface temperature
When selecting the valve, the surface temperature requirement of the valve must be taken into account.
It must be min. 25 °C lower than the temperature necessary to initiate an explosion of an explosive
atmosphere of a given composition. If the initiation temperature is exceeded an explosion will occur.
DANGER
Handling in an explosive atmosphere
It is forbidden to install, disassemble, repair or replace the valve in an exlosive atmosphere.
Risk of explosion.
DANGER
Maximum operating pressure
The valve may be used for a maximum pressure of 350 bar in the ports P, A, B and 100 bar in port T.
If the maximum pressure is exceeded there is a risk of damage to the valve. Exceeding the pressure value may
cause the valve to rupture I.e. exceeding 525 bar in ports P, A, B and 150 bar in port T.
DANGER
Maximum hydraulic output
Section 4.6 of the datasheet shows the operating limit curves for each type of spool valve. The hydraulic
performance is provided as the product of the working pressure and the flow rate. If the instant power exceeds
the curve limit, the valve may lose function. The spool is subjected to excessive hydrodynamic forces, the valve
spool will not be switched over and control of the appliance will be lost.
WARNING
Valve installation
The valve may only be mounted to a sufficiently machined surface with a specified connection pattern. The
specified sealing rings must be inserted, undamaged into the body recesses. The valve is fastened with four
M5x45 ISO 4762 bolts tightened to a tightening torque of 8.9+1 Nm. Otherwise, there is a risk of leakage of
the working fluid and loosening of the valve by pressure (For details, see paragraph 7.2 Product installation)
CAUTION
Maximum operating temperature
The maximum operating temperature must not exceed the temperature range allowed in paragraph 4.4 Basic
technical parameters or in the datasheet. Both the temperature of the operating fluid and the ambient tempera-
ture significantly influence:
a) the surface temperature of the valve
b) the temperature of the solenoid coil winding - there is a risk of a reduction in hydraulic performance
c) the seal material - risk of seal damage and leakage of the working fluid.
CAUTION
Surface temperature of the valve
The surface temperature of the valve can exceed 100 °C due to the temperature of the working fluid and pressure
loss in the valve being converted to heat. Do not touch the surface of the valve when the circuit is operational,
even after switching off. Wait until it has cooled down to a safe temperature. There is a risk of burns.
CAUTION
Working fluids used
Valves may only be used for normal working fluids, especially hydraulic oils (see chapter 4. Product description).
It is forbidden to use the following as working fluids, in particular:
› water and aquesous solutions that will cause corrosion and loss of valve function
› liquids which are flammable or explosive, the heating of which may cause fire or explosion when
passing through the valve
› aggresive liquids (e.g. acids and hydroxides) which will cause damage to the valve and loss of
function.
The flash point of the used working fluid must be at least 50 K higher than the maximum allowed of surface
temperature of the valve in the given temperature class.
DANGER
Electric shock
The solenoid coil is an electrical device that should be wired by a person with appropriate electrical qualifica-
tions. Before wiring the solenoid, check the parameters of the power supply, the integrity of the cable and the
solenoid. There is a risk of electric shock.
CAUTION
Electrical supply values
The solenoid coil is energised by the electrical current passing through the winding. The values of the electrical
supply must not exceed the values indicated on the coil. There is a risk of losing solenoid function.
3.3 Risks associated with the electrical part of the valve
Operating instructions_RPER2X3-06_15312_1en_09/2023
Page 12 www.argo-hytos.com
4. Product description
The hydraulic part of the valve consists of a cast iron body (1) with output ports on the lower base, a hardened steel spool and return springs that
hold the spool in its base position. The spool is adjusted to the working positions by means of solenoids (2) certified for explosive atmospheres. The
solenoid coils are fixed to the actuating system with hexagonal nut (3). The body of the manual lever control (4) is built between the solenoid and
the hydraulic part. When the valve is operated by the solenoid, the lever remains in its basic position due to the backdrop and does not reduce its
performance. Thread adapter (5) with an optional thread is used for connecting the power cable, e.g. using a suitable cable gland.
CAUTION
Use of the emergency manual control is forbidden when the valve solenoids are operational.
If the valve is operated by solenoids do not use the emergency manual control of the valve spool.
Valve damage and loss of function may result.
The emergency manual spool position control is used to reposition the spool in the event of loss of solenoid function or in the event of power failure
to the coils to achieve a safe position of the operated mechanism. The use of the manual emergency control is limited to a maximum pressure of 100
bar in the T-port.

6. Target group of users
All of the above activities related to this valve, in particular installation and connection to the hydraulic circuit, require specialist technical knowledge
and experience in the field of hydraulics. The minimum level of competence required is CETOP level 2. This level is generally defined as performing a
variety of activities that require an understanding of technical factors and contexts. This may lead to the need for correct interpretation (e.g.
tolerances, operating methods) or the application of various non-repetitive procedures. This may require the performance of checks, simple analysis

WARNING
Slippery valve surface
The valve contains a small amount of residual oil after a hydraulic function test carried out by the manufacturer.
If the surface of the unpacked valve is contaminated with oil, remove the oil using a cleaning cloth. A slippery
valve surface can cause the valve to fall during handling and cause minor injury or damage to the valve.
7. Operating instructions broken down by product life stage
The valve is packaged in vacuum shrink-wrapped PE foil and protected against moisture and dust as standard. The P, A, B, T ports on the base are
additionally protected by a plastic (PE) shipping plate. An identification label is affixed to the packaging.
The products should only be stored for the necessary time at a temperature of 0 to +30 °C in a dry place with a relative humidity of up to 65 %.
After extended periods of storage, we recommend checking the product for corrosion damage, replacing seal at the base of the body and flushing
the product with clean oil before connecting it to the hydraulic circuit.
7.1 Transportation and storage of the product
Check that the valve type on the identification plate is correct. Cut the packaging with scissors and carefully remove the valve from the packaging.
Unpack the valve in a clean place and prevent contamination of the valve. The packaging is made of PE and can be easily contaminated with residual
hydraulic oil from the valve. Dispose of the packaging in accordance with applicable environmental regulations.
The mounting position of the valve is arbitrary. However, if vibrations or shocks are applied to the valve during operation, they must not be applied in
the direction of the spool axis.

› Assemble the cable gland according to the manufacturer’s instructions so that the cable is sufficiently secured against pulling out by external force
and displacement by gases in the event of an explosion in the inner space of the coil casing. The inner space of the coil casing must be sufficiently
sealed.
› Fit a steel plug with seal into the free hole in the coil casing and tighten it to the specified torque of 30±5 Nm using an inbus wrench A/F 10.
Secure the position of the thread adapter and the steel plug against loosening with M3x4 grub screws and tighten them to a torque of 0.4±0.1
Nm using an inbus wrench A/F 1.5 mm.
› After mounting the valve, the surface of the coil must be grounded by connecting the ground wire to the terminal on the top surface of the coil
casing using an M5x10 screw. Tighten the screw to a tightening torque of 2.2±0.2 Nm using an 8 mm wide screwdriver.
Connecting the wires to the terminal block:
› Remove the insulation from the end of the cable so that when the cable is fixed in the cable gland, the insulated part of the cable sufficiently
extends into the inner space of the terminal block.
› Strip the ends of the wires to a length of 5 to 6 mm.
Release the clamp by pressing the lever against the spring in the direction of the arrow and insert a wire with a cross section of 0.5 to 1.5 mm2.
Releasing the lever secures the wire. The right clamp is for the earth wire.
› Make sure that the conductors are sufficiently secured in the clamps and are not in danger of loosening.

WARNING
Correct installation of the valve
The four sealing rings on the base of the body must be undamaged and inserted into the recesses, the
connection surface of the plate sufficiently machined and undamaged, the valve must be fixed with four
fastening bolts tightened to the specified torque. Failure to meet these conditions for proper valve installation
may result in leakage of working fluid.
The solenoid windings heat up during operation. Effective external cooling must be provided to ensure that the maximum winding temperature is not
exceeded, by not exceeding the maximum fluid and ambient temperature and by maintaining minimum volume of the connection block. A valve
body volume of (152.5 cm3) is sufficient for one manifold. If several valves that can be switched simultaneously are connected on the connection
plate, a distance of at least 10 mm must be maintained between the bodies of adjacent valves (see fig).

WARNING
Switching solenoids
Directional control valves with two solenoids, coils must not be switched at the same time.
There is a risk of damaging the valves.
WARNING
Coil cooling
Coil cooling takes into account the cooling surface of the hydraulic part of the valve.
Do not power separately disassembled coils. Excessive winding heat, insulation damage and short circuiting
between coils may occur. For the same reason, the surface of the coils must not be covered, exposed to direct
heat sources or sunlight. The valve must not be closed in a tight space without ensuring air circulation.
7.3 Commissioning
Before commissioning the hydraulic ciruit, check that the valve is correctly mounted on the connection plate and that electrical supply cables are
correctly connected. The valve is not to be adjusted. Test operation should be conducted without the pressence of an explosive atmosphere. After the
hydraulic circuit has been commissioned, check the valve for leaks. Simply verify the directional control valve function, repositioning the spool by alter-
nately switching the solenoids and monitoring the movement of the appliance or the amount of pressure in the appliance branches (ports A and B).
7.4 Normal operation
During normal operation , the directional control valve spool is adjusted by the solenoids. Normal operation of the system does not require any
manipulation of the valve.
DO NOT exceed the MAXIMUM PARAMETERS, shown in table 4.4.
OBSERVE THE OPERATIONAL RESTRICTIONS AND AVOID THE RISKS , referred to in paragraph 3.
USE PROTECTIVE EQUIPMENT
When working with hydraulic fluid, it is recommended to wear safety goggles, protective rubber gloves and sturdy shoes with non-slip soles.

7.5 Extraordinary and emergency situations
In the event of a power failure to the solenoids or a coil failure, the centering spring will return the valve spool to its base position.
Based on the results of the risk analysis, the following potential faults have been identified:
› External valve leakage due to seal damage associated with a working fluid leak.
› Loss of valve function, resulting in loss of control of the appliance.
› Mechanical damage to the electrical part of the valve, including the cable.
Defective valves must be replaced/repaired.
DANGER
Shutdown of electrical power, pressure source and circuit relief
In the event of an emergency, immediately shut off the electrical power supply to the control solenoids and
the pressure source (pump). Relieve all parts of the hydraulic circuit including the hydraulic accumulators by
connecting them to the tank. A malfunctioning valve may cause a dangerous operating situation due to loss
of control. A damaged electrical part can initiate an explosion.
DANGER
Prohibition of handling and repair in explosive atmospheres
A defective valve must not be repaired or dismantled when an explosive atmosphere is present.
There is a risk of initiating an explosion.
WARNING
Check pressure relief part of the circuit
Always ensure that the circuit is depressurised before intervening in the hydraulic circuit, for example before
removing a valve. Otherwise there is a risk of leakage of working fluid and contamination of persons.
WARNING
Surface temperature
Before starting disassembly, make sure that the surface of the valve and solenoid coils has cooled to a low
enough temperature to prevent skin burns.
ENVIRONMENTAL PROTECTION
Spilled working fluid must be removed immediately, e.g. with suitable absorbents, contaminated parts of the perimeter cleaned,
contaminated objects in the vicinity cleaned or disposed of.
Contaminated objects and residues of leaked working fluid must be disposed of in accordance with the applicable environmental
regulations.
FIRST AID
Electric shock
› Switch off the power supply immediately
› Make sure the casualty is breathing.
› Call emergency medical services
› If the casualty is not breathing, initiate measures to restore basic life functions according to first aid abilities (CPR, artificial
respiration) and equip the workplace (defibrillator) with life-saving equipment.
Contamination by hydraulic working fluid
If contamination of persons occurs, contaminated parts of clothing must be removed immediately and the skin thoroughly washed
with soap or treated with a suitable cream.
If the eyes are contaminated, flush them with clean water and seek medical attention. Seek medical attention also in case of
accidental ingestion of working fluid or skin allergic reaction to splashes of working fluid.
7.6 Repairs carried out by specialist
A suitably qualified user is authorised to replace the complete valve, the seals at the base of the valve body, which are supplied as a spare set.
Operating instructions_RPER2X3-06_15312_1en_09/2023
Page 20 www.argo-hytos.com
7.6.2 Replacing the sealing rings at the base of the valve body
In case of leaks in the dividing plane, the sealing rings must be replaced with new ones. The disassembly and reassembly procedure is similar.
› Ensure that no explosive atmosphere is present during the repair (see also 7.5).
› Switch off the pressure source (pump) of the hydraulic circuit (see also 7.5).
› Lighten the hydraulic circuit including the accumulators by connecting it to the tank (see also 7.5).
› Ensure that the hydraulic circuit is depressurised (see also 7.5).
› Switch off the electrical supply to the directional control valve solenoids (see also 7.5).
› Make sure that the surface of the valve and solenoid coils is cooled to a low enough temperature to prevent skin burns (see also 7.5).
› Clean the surface and surroundings of the directional control valve.
› Loosen and unscrew the four fastening screws M5x45 DIN 912 using the inbus wrench A/F 4. Carefully remove the valve from the
connection plate.
› Allow the remaining working fluid from the valve to drain into the prepared smaller container.
› Using a small screwdriver, remove the sealing rings from the recess in the body.
› Work carefully to avoid damaging the sealing surfaces.
› Clean the connection surfaces of the valve body and plate. Check them for damage.
› Insert new sealing rings into the recesses in the valve body so that they do not fall out when the valve is reassembled.
› Insert the four fastening screws into the holes in the valve body and fasten the valve to the plate using the inbus wrench A/F 4. Tighten
the screws in a crosswise sequence to the specified torque of 8.9 + 1 Nm. Uneven tightening may cause deformation of the body and
unreliable valve function.
› If any of the fixing screws are damaged, replace them.
WARNING
Valve mounting screws
The screws must be high tensile screws (SCREW M5x45 DIN 912 10.9), preferably from the valve manufacturer.
A screw of normal tensile can be broken due to the high pressure in the hydraulic circuit and can cause
massive leakage of the working fluid.
A defective valve that is not caused by a malfunctioning solenoid coil must be removed and replaced with a new one.
Repairs to a defective valve may only be carried out by the manufacturer.
When replacing the defective valve with a new one, proceed as follows:
› Ensure that no explosive atmosphere is present during the repair period (see also 7.5).
› Switch off the pressure source (pump) of the hydraulic circuit (see also 7.5).
› Relieve the hydraulic circuit including the accumulators by connecting it to the tank (see also 7.5).
› Ensure that the hydraulic circuit is pressure-free (see also 7.5).
› Switch off the electrical supply to the directional control valve solenoids (see also 7.5).
› Ensure that the surface of the valve and solenoid coils is cooled to a low enough temperature to prevent skin burns (see also 7.5).
› Disconnect the electrical supply cable to the coils (see 7.6.3).
› Switch off the electrical supply to the position sensor (if the valve is equipped with one) and disconnect the M12x1 connector.
› Remove the coil surface ground wire by loosening the M5x10 ground screw.
› Clean the surface and surroundings of the dirctional control valve.
› Allow the remaining working fluid from the valve to drain into the prepared smaller container.
Remove residual working fluid from the dismantled defective valve, seal the ports with a shipping plate and package it to prevent mechanical damage
and contamination of the area outside the package during transport. Send the packaged valve with a description of the manifestation of the defect
to the manufacturer. A new valve is warranted by the manufacturer for 1 year. However, a claim may not be accepted by the manufacturer if the
valve is mechanically damaged, the seal material is damaged by aggressive liquid, or the valve has been shown to have been used improperly and not
in accordance with these instructions of use.
7.6.1 Replacing a defective valve
› Check that the coil cables in the cabel gland and the earth wires are properly secured to ensure that they are not loose when the valve is handled.
› After the repair, verify the new seals are tight and the valve is working properly.
7.7 Product maintenance
During normal operation, keep the valve clean and free of dust deposits on the surface. Deposits both impair cooling of the valve and coils and can
form flammable layers prone to ignition. Choose the surface cleaning interval according to the dustiness of the environment so that the thickness of
the deposited dust layer does not exceed 3 mm. Depending on the conditions of use, check the hydraulic circuit for leaks, the electrical parts
including cables for damage and the valve and position sensor for correct operation at appropriate intervals. The check should be performed every
time the device is started, but at least once a week during long-term operation.
