1. Based on legislative requirements, all operators in the logistics chain, from the manufacturer of the certified Ex solenoid coil to the end user
of the complete equipement, are obliged to make and maintain traceability records of Ex products, enabling, if necessary, the withdrawal
of products of certain serial numbers from the market due to defects of non-conformities, endangering safety of use in an aexplosive
atmosphere. In practice, this means keeping records of the assignment of Ex coil/valve identification numbers to the identification numbers
of the operators immediately down the logistics chain.
2. To meet the requirement for traceability of Ex products, it is necessary to keep product type labels legible throughout their technical life.
Mandatory traceability

Glossary of technical terms used
›A hydraulic mechanism is one in which energy is transmitted via the compressive 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 control 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 product
The RPEX3-06 hydraulic 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.
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 mine gas, 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:
Class I, mines, where the explosive atmosphere of mine gas is prodominantly methane
The valve has a high degree of protection (EPL = Mb), which makes iniation unlikely during the interval between gas discharge and valve shutdown.
It is designed for category M2 devices that remain off after gas discharge.
Class II, where the explosive atmospere consists of gasses other than mine gas
The valve has a high degree of protection (EPL = Gb) which allows the valve to be used in zones 1 and 2. There is a risk of explosion.
The valve is certified for all gas groups - IIA (typical is methane), IIB (typical is ethylene) and IIC (typical is hydrogen).
Class III, where the explosive atmosphere consists of dust and combustible flammable particles
The valve has a high degree of protection (EPL = Db) which allows the valve to be used in zone 20. There is a risk of explosion.
The valve is certified for all dust groups - IIIA (combustible flying particles), IIIB (non-conductive dust) and IIC (conductive dust).

The valves are available in three surface temperature classes:
T4 with a maximum surface temperature of 135 °C
T5 with a maximum surface temperature of 100 °C
T6 with a maximum surface temperature of 85 °C
The use of the valve in the temperature class is subject to the maximum supply voltage of the coil not being exceeded, the working
fluid temperature not being exceeded and the ambient temperature not being exceeded (see Table 4.4 Basic technical parameters)
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 type of protection is to pot the coil with potting compound „m“ (EN 60079-18, IEC 60079-18). For a DC-powered coil, protection is
combined by potting the coil with „m“ using a terminal block with „e“ certification (EN 60079-7, IEC 60079-7).
In addition, a fixed „t“ closure is used for dust (EN 60079-31, IEC 60079-31).

The safety of the non-electrical parts has been ensured and assessed according to ISO 80079-36 and ISO 80079-37 and EN ISO/IEC 80079-38 .
› The moving parts, the spool/cone, armature and pin of the control system, perform a sliding motion in a space separated by a seal from the
surround ing environment and flooded with working fluid.
› Not exceeding the maximum surface temperature of the given temperature class is conditioned by not exceeding the maximum temperature
of the working fluid (70 °C), the maximum ambient temperature (see table 4.4 Basic technical parameters) and the nominal voltage of the coil.
› The valve body and spool body are of robust construction, sufficiently resistant to destruction by mechanical shock.
(Valve body impact resistance test performed according to EN IEC 60079-0 paragraph 26.4.2: two impacts with a weight with a hardened head of
diameter D25 mm, weighing m = 1 kg, falling from a height of 0.7 m, with a total potential energy of 7 J)
› The hydraulic section has sufficient compressive strength, tested at 1.5 times the maximum operating pressure of the fluid.
› The construction materials used meet the requirements for limited content of certain elements to prevent the formation of electrical cells and
excessive corrosion.
› The surface materials used do not produce sparks during mechanical impacts.
› The sliding rod of the manual emergency control N7 of the pilot valve is protected by a sealing sleeve against the ingress of contaminating
particles, especially hard particles, which could create an initiating spark.

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 210 bar in portT.
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 315 bar in port T.
DANGER
Maximum hydraulic output
Section 4.6 of the product catalogue 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 will not stop and as a result ,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 product catalogue. Both the temperature of the operating fluid and the ambient
temperature 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.

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 Exceptional 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
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.
Defective valves must be replaced/repaired.
